Product Details

CC-TD0R01 51308376-175 Product Description

The Honeywell CC-TD0R01 (Part No. 51308376-175) is a C300 series digital output relay module engineered for energy-conscious distributed control system (DCS) environments. Designed to operate within Honeywell's Experion PKS platform, this module delivers precise, low-latency relay switching that directly supports load management, motor control sequencing, and energy-optimised actuation across continuous and batch production lines. With a verified 12-month warranty and full pre-shipment functional testing, the CC-TD0R01 is a dependable choice for facilities targeting reduced energy waste, lower thermal load, and higher equipment utilisation rates.

Industrial facilities operating high-density I/O architectures face a persistent challenge: unnecessary energy draw from poorly sequenced output switching, oversized relay banks, and uncoordinated actuator control. The CC-TD0R01 addresses this directly by providing deterministic relay output control that integrates cleanly with the C300 controller's scan cycle, ensuring outputs are energised only when process logic demands — eliminating parasitic load and reducing heat generation in control panel enclosures.

The CC-TD0R01 does not operate in isolation — its energy-control value is amplified when deployed as part of a coordinated automation architecture. Within a typical smart production line, this module interfaces directly with the Honeywell C300 Controller, which manages the scan cycle and output scheduling logic. The C300's deterministic execution ensures that relay outputs are toggled with precision, preventing the energy spikes associated with uncoordinated switching in legacy relay panels.

On the drive side, the CC-TD0R01 relay outputs are commonly used to issue run/stop commands to variable frequency drives (VFDs) and servo drive systems, enabling soft-start sequencing that reduces inrush current and mechanical stress on motors. When paired with a Honeywell PM I/O power monitoring module or a third-party power measurement unit on the same backplane, engineers gain real-time visibility into load draw per output channel — a critical input for energy management system (EMS) dashboards and SCADA trending.

The module's relay contacts are also used to control industrial solenoid valves, motor contactors, and pneumatic actuators — all of which benefit from the CC-TD0R01's clean switching characteristics. In facilities running Honeywell Experion PKS SCADA, output state data from the CC-TD0R01 feeds directly into historian logs, enabling predictive maintenance algorithms to flag relay wear before failure occurs.

For I/O expansion, the CC-TD0R01 is typically rack-mounted alongside Honeywell CC-TDIL01 digital input modules and CC-TAIX01 analogue input modules, forming a balanced I/O cluster that supports both sensing and actuation within a single C300 node. This co-location reduces cabling runs, lowers signal latency, and contributes to a more thermally stable control cabinet — all of which translate to measurable energy savings over a production year.

HMI integration via Honeywell Experion Station or compatible third-party HMI panels allows operators to monitor relay output states in real time, enabling rapid response to abnormal load conditions without requiring field intervention. Combined with industrial Ethernet communication modules supporting PROFINET or Modbus TCP, the CC-TD0R01's status can be surfaced to plant-level MES and ERP systems for production efficiency reporting.

In smart manufacturing environments, energy optimisation is not a single-point solution — it is a system-level discipline. The Honeywell CC-TD0R01 contributes to this discipline at the actuation layer, where poorly managed relay outputs are a common but overlooked source of energy waste and thermal load accumulation.

By integrating the CC-TD0R01 into a C300-based DCS architecture, production engineers gain the ability to implement load-shedding sequences during low-demand periods, staggered motor start routines to flatten peak demand curves, and output inhibit logic that prevents unnecessary relay energisation during standby or changeover phases. These strategies, when executed through the C300's deterministic control engine, can reduce a facility's peak electrical demand by a measurable margin — directly impacting energy billing and carbon reporting metrics.

Thermal load reduction is another key benefit. Relay modules that switch frequently under poorly optimised logic generate heat that accumulates in control enclosures, increasing cooling system load and accelerating component ageing. The CC-TD0R01's efficient switching profile, combined with proper scan-cycle tuning in the C300 controller, minimises unnecessary relay cycling — extending module service life and reducing HVAC demand in the control room.

From a production line rhythm (takt time) perspective, the CC-TD0R01's low-latency relay response ensures that actuator commands are executed within the process control window, preventing the timing drift that causes line stoppages, product rejects, and energy-intensive restart sequences. Stable, predictable output switching is foundational to maintaining consistent production throughput without energy penalties.

Pre-shipment functional testing on every CC-TD0R01 unit ensures that relay contact resistance, switching speed, and channel isolation all meet Honeywell's original specification — eliminating the risk of field failures that trigger unplanned downtime, emergency maintenance energy surges, and production loss. Stock availability is maintained for rapid dispatch, supporting MRO procurement teams managing just-in-time spare parts strategies.

Q1: How does the CC-TD0R01 contribute to energy savings in a DCS environment?The CC-TD0R01 enables demand-driven relay switching controlled by the C300's deterministic scan cycle. This eliminates unnecessary relay hold current, reduces panel heat generation, and supports load-shedding and staggered-start strategies that lower peak energy demand across the production line.

Q2: Is the CC-TD0R01 compatible with Honeywell Experion PKS and third-party SCADA systems?Yes. The CC-TD0R01 is a native C300 series module fully compatible with Honeywell Experion PKS. Output state data can be surfaced to third-party SCADA platforms via OPC-DA/UA or Modbus TCP communication modules installed in the same C300 node, enabling cross-platform energy monitoring and historian integration.

Q3: What is the recommended replacement or upgrade path for ageing relay output modules in a C300 system?The CC-TD0R01 (51308376-175) is the current-generation relay output module for C300 architectures. For facilities migrating from older Honeywell TDC 3000 or HPM I/O systems, a full I/O mapping review is recommended before substitution. Our technical team can assist with compatibility verification prior to order confirmation.

Q4: What testing and warranty coverage is included with each unit?Every CC-TD0R01 unit undergoes full functional testing prior to shipment, covering relay contact integrity, channel isolation, and communication handshake with C300 controller firmware. A 12-month warranty is provided from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. Expedited stock is available for urgent MRO and project procurement requirements.
