Product Details

51308380-175 CC-SDOR01 Product Description

The Honeywell CC-SDOR01 (Part No. 51308380-175) is a System-Ready Digital Output Relay Module engineered for the Experion PKS C300 Distributed Control System platform. Designed to operate within Honeywell's Series C I/O architecture, this module delivers reliable relay-switched digital outputs for field device actuation across demanding industrial environments. Its role within the control architecture extends far beyond simple switching — the CC-SDOR01 serves as a critical execution-layer component that bridges the controller's command logic with physical field actuators, ensuring deterministic signal delivery, electrical isolation, and long-term operational stability.

In a fully integrated Experion PKS architecture, the CC-SDOR01 is mounted on a Series C I/O Link carrier assembly alongside complementary I/O modules. The module communicates upstream through the C300 Controller via the FTE (Fault Tolerant Ethernet) backbone, enabling high-speed, deterministic data exchange between the field execution layer and the supervisory control layer. This architecture supports both simplex and redundant configurations, allowing engineers to design systems with the appropriate level of fault tolerance for their process criticality requirements.

The CC-SDOR01 integrates seamlessly with the broader Experion PKS ecosystem. In a typical control cabinet deployment, it operates alongside the CC-PDOB01 Digital Output Module, CC-PDIL01 Digital Input Module, and CC-PAIX01 Analog Input Module — all mounted on shared carrier assemblies connected to the C300 Controller. Power distribution is managed through the CC-PWR001 Power Supply Module, which provides regulated 24 VDC to the I/O subsystem. For applications requiring communication gateway functionality, the CC-SDOR01 coexists with the ENET-2 Ethernet Interface Module and the ControlNet CNI Module, enabling multi-protocol integration across plant-wide SCADA and MES systems.

System redundancy is a core design consideration for the CC-SDOR01's deployment environment. In redundant C300 configurations, the module's carrier assembly supports hot-standby I/O redundancy, ensuring that a single module failure does not interrupt process control. This capability is particularly valuable in continuous process industries such as oil refining, chemical processing, and power generation, where unplanned shutdowns carry significant operational and safety consequences. The module's relay output design also provides inherent electrical isolation between the controller logic and field wiring, protecting sensitive control electronics from voltage transients and ground loops common in industrial field environments.

From a system architecture perspective, the CC-SDOR01 occupies the execution layer of the control hierarchy. Above it, the C300 Controller processes control strategies defined in Honeywell's Control Builder engineering environment. Below it, field actuators — including motor starters, solenoid valves, and alarm annunciators — receive switched relay contacts for on/off control. This layered architecture ensures clean signal separation between the control logic layer, the I/O execution layer, and the field device layer, simplifying both commissioning and long-term maintenance.

For HMI integration, the CC-SDOR01's output states are reflected in real time on Experion PKS Operator Stations running the HMIWeb Display Builder environment. Operators can monitor relay output status, acknowledge alarms, and initiate manual overrides directly from the HMI, providing full operational visibility across the execution layer. This integration extends to Honeywell's PHD (Process Historian Database) for long-term trend analysis and compliance reporting.

Maintenance and diagnostics are streamlined through Experion PKS's built-in module health monitoring. The C300 Controller continuously polls the CC-SDOR01 for module status, contact wear indicators, and communication health metrics. Fault conditions are surfaced immediately in the Experion Station alarm management system, enabling maintenance teams to respond proactively before process disruptions occur. This diagnostic transparency significantly reduces mean time to repair (MTTR) and supports predictive maintenance programs in high-availability facilities.

All CC-SDOR01 units supplied by NANKMOS are sourced from verified inventory channels, subjected to pre-shipment functional testing, and covered by a 12-Month Warranty. Each module is inspected for firmware version compatibility, relay contact integrity, and connector condition prior to dispatch. Global shipping is supported with full export documentation, ensuring compliance with international trade requirements for industrial automation components.

The CC-SDOR01 achieves its full operational value when deployed as part of a complete Experion PKS control architecture. In a standard C300-based control system, the module is installed on a Series C I/O Carrier alongside the CC-PDOB01 (Digital Output Module) for transistor-switched outputs and the CC-PDIL01 (Digital Input Module) for field status feedback — together forming a complete digital I/O subsystem for discrete process control. Analog process variables are handled by the CC-PAIX01 (Analog Input Module) and CC-PAOX01 (Analog Output Module), which share the same carrier infrastructure and communicate through the same C300 I/O Link.

The C300 Process Controller serves as the central processing node, executing control strategies at scan rates appropriate for the process dynamics. In redundant configurations, a secondary C300 Controller operates in hot-standby mode, with automatic bumpless transfer ensuring continuity of control during primary controller faults. Power integrity across the I/O subsystem is maintained by the CC-PWR001 Power Supply Module, which provides regulated, filtered 24 VDC to all carrier-mounted modules including the CC-SDOR01.

For plant-wide communication integration, the Experion PKS architecture incorporates the ENET-2 Ethernet Interface Module for FTE (Fault Tolerant Ethernet) connectivity and the CNI ControlNet Interface Module for legacy ControlNet device integration. These communication modules enable the CC-SDOR01's output states to be monitored and commanded from remote Experion Operator Stations, DCS engineering workstations, and third-party SCADA systems via OPC-DA/UA interfaces. In facilities requiring fieldbus integration, the FF-HSE Linking Device bridges FOUNDATION Fieldbus H1 segments to the Experion FTE backbone, extending the architecture's reach to smart field instruments.

HMI visualization is delivered through Experion PKS Operator Stations running HMIWeb displays, providing real-time relay output status, alarm management, and manual override capability. For advanced process analytics, the Honeywell PHD Historian archives CC-SDOR01 output state transitions for compliance reporting, root cause analysis, and predictive maintenance programs. This end-to-end integration — from relay contact actuation at the CC-SDOR01 through to historian archiving and HMI visualization — exemplifies the system coherence that defines the Experion PKS platform.

Oil & Gas and Petrochemical Processing: In upstream and downstream hydrocarbon processing facilities, the CC-SDOR01 provides relay-switched outputs for emergency shutdown (ESD) valve actuation, pump motor starter control, and flare ignition systems. Its electrical isolation characteristics protect the C300 Controller from the high-energy transients common in hazardous area field wiring, while its integration with Experion PKS's Safety Manager platform supports SIL-rated safety instrumented function (SIF) architectures.

Power Generation and Utilities: In thermal power plants, combined-cycle facilities, and utility substations, the CC-SDOR01 controls breaker trip/close relays, cooling system actuators, and auxiliary equipment contactors. Its deterministic relay switching, combined with the C300 Controller's high-speed scan capability, ensures that protective relay commands are executed within the timing requirements of power system protection schemes.

Q1: Is the CC-SDOR01 compatible with both simplex and redundant C300 Controller configurations? Yes. The CC-SDOR01 is designed for deployment on Series C I/O Carrier assemblies that support both simplex and redundant I/O configurations. In redundant configurations, the carrier assembly provides hot-standby I/O redundancy at the module level, with the C300 Controller managing automatic switchover in the event of a module fault. This redundancy architecture is transparent to the control strategy and requires no special programming in Control Builder. NANKMOS supplies CC-SDOR01 modules verified for compatibility with current C300 firmware revisions, and our technical team can advise on carrier assembly selection for specific redundancy requirements.

Q2: What are the key considerations for integrating the CC-SDOR01 into an existing Experion PKS system during a brownfield expansion? Brownfield integration of the CC-SDOR01 requires verification of the existing C300 Controller firmware version, I/O Link capacity, and carrier assembly slot availability. The module must be assigned a unique I/O Link address within the C300's I/O configuration, and its channel assignments must be defined in Honeywell Control Builder before downloading to the controller.
