TRICONEX 9668-110 Termination Board

Product Details

9668-110 Product Description

The TRICONEX 9668-110 is a field-proven termination board engineered for Tricon Triple Modular Redundant (TMR) safety systems, delivering deterministic I/O signal routing, robust protocol bridging, and seamless integration across the full industrial data chain. Designed for mission-critical process automation environments — including oil and gas, petrochemical, power generation, and advanced manufacturing — the 9668-110 serves as the physical and logical backbone connecting field instruments to the Tricon safety controller, enabling real-time data acquisition, alarm management, and remote diagnostics across distributed control architectures.

In a modern smart factory, data integrity begins at the termination layer. The 9668-110 ensures that every analog and digital signal from pressure transmitters, flow sensors, temperature probes, and actuator feedback loops is cleanly terminated, properly conditioned, and reliably forwarded to the Tricon main chassis. This eliminates signal noise, ground loops, and wiring errors that can compromise safety instrumented function (SIF) performance — a critical requirement under IEC 61511 and IEC 61508 functional safety standards.

The 9668-110 termination board sits at the critical junction between field instrumentation and the Tricon safety controller, forming the first link in a layered industrial data chain. Field devices — including HART-enabled pressure transmitters, thermocouple inputs, solenoid valve feedback signals, and discrete limit switches — connect directly to the 9668-110's screw-terminal field wiring interface. From there, conditioned signals pass through the Tricon I/O module (such as the TRICONEX 3703E Digital Input Module or 3805E Analog Input Module) into the Tricon main processor chassis.

Within the Tricon chassis, the TRICONEX 4351B Main Processor Module executes the safety logic in TMR (Triple Modular Redundant) architecture, continuously voting across three independent processing paths to ensure fault-tolerant control. The processed data is then forwarded upstream via the TRICONEX 4119A Network Communication Module, which bridges the Tricon safety domain to the plant DCS or SCADA network using Modbus TCP or OPC DA/UA protocols.

At the SCADA layer, historians and visualization platforms — such as those integrated with Wonderware System Platform or Ignition SCADA — receive real-time process values, alarm states, and diagnostic data from the Tricon system. Operators at HMI workstations can monitor SIF status, view trip logs, and acknowledge alarms without interrupting the safety function. For remote sites, an industrial edge gateway (such as a Moxa MGate or HMS Anybus gateway) can further translate Modbus data to MQTT or IEC 61850 for cloud-based monitoring and predictive maintenance platforms.

The 9668-110 also supports integration with emergency shutdown (ESD) panels, fire and gas (F&G) detection systems, and burner management systems (BMS), all of which rely on clean, noise-free termination to maintain SIL 2 or SIL 3 integrity. When paired with a TRICONEX 3008 Communication Module or a Tricon Enhanced Intelligent SAM (ESAM), the system can support peer-to-peer Tricon-to-Tricon communication for large-scale distributed safety architectures spanning multiple process units.

For power infrastructure, the Tricon chassis is typically supported by a TRICONEX 8312 Power Supply Module, ensuring stable, redundant DC power delivery to all I/O and communication modules — including the termination board interface. This end-to-end architecture, from field wiring through the 9668-110 termination board to the SCADA historian, represents the complete smart factory data link for safety-critical process automation.

Protocol Fragmentation: Many brownfield plants operate legacy field devices using 4–20 mA analog signals or HART alongside newer Modbus or PROFIBUS instruments. The 9668-110, as part of the Tricon I/O subsystem, provides a standardized termination interface that accommodates mixed signal types, reducing the need for external signal converters and simplifying wiring documentation.

Data Silos and Visibility Gaps: Without a properly terminated and validated I/O layer, process data from field instruments cannot be reliably aggregated at the SCADA or DCS level. The 9668-110 ensures signal integrity at the source, enabling accurate data collection that feeds real-time dashboards, trend analysis, and KPI reporting for production transparency.

Remote Monitoring and Diagnostics: In geographically distributed facilities — offshore platforms, pipeline stations, or multi-unit refineries — remote access to safety system diagnostics is essential. The 9668-110, integrated within the Tricon architecture, supports remote diagnostic access via TriStation 1131 engineering software, allowing maintenance engineers to review I/O channel health, signal levels, and fault histories without on-site visits.

Alarm Management and Traceability: Unstructured alarm floods are a leading cause of operator error in process plants. The Tricon system, anchored by reliable termination through the 9668-110, provides structured alarm prioritization, time-stamped event logging, and SOE (Sequence of Events) recording — enabling post-incident analysis and regulatory compliance reporting.

System Scalability: As production capacity expands, additional I/O points can be added to the Tricon chassis by installing additional termination boards and I/O modules without redesigning the safety logic. The 9668-110's modular form factor supports incremental system growth aligned with plant expansion timelines.

Q1: What communication protocols does the TRICONEX 9668-110 support in a SCADA-integrated environment? The 9668-110 is a termination board within the Tricon TMR I/O subsystem. At the system level, the Tricon architecture supports Modbus RTU, Modbus TCP, and OPC DA/UA (via the Tricon Network Communication Module), enabling seamless data exchange with SCADA platforms, DCS historians, and HMI workstations. HART pass-through is also supported for field device diagnostics.

Q2: How does the 9668-110 contribute to network stability and signal integrity in safety-critical applications? The 9668-110 provides a dedicated, noise-isolated termination interface between field wiring and the Tricon I/O module. Its design minimizes ground loops, EMI interference, and wiring cross-talk — all of which can cause spurious trips or missed alarms in SIL-rated safety loops. Proper termination at this layer is foundational to maintaining SIL 2/SIL 3 performance across the full safety instrumented function.

Q3: Can the TRICONEX 9668-110 be integrated with third-party SCADA or edge computing platforms? Yes. When the Tricon system is equipped with a Network Communication Module (such as the TRICONEX 4119A), it exposes process data via Modbus TCP or OPC DA/UA, which is compatible with leading SCADA platforms (Ignition, Wonderware, iFIX) and industrial edge gateways. This enables cloud-based monitoring, remote diagnostics, and data visualization without modifying the safety logic.

Q4: What is the warranty and pre-shipment testing policy for the TRICONEX 9668-110?
