TRICONEX 3623T 16-Point TMR Supervised Digital Output Module (120 VDC) for Tricon SIS

Product Description

The TRICONEX 3623T is a high-integrity 16-point supervised digital output module, a core component of the TRICONEX Tricon triple modular redundant (TMR) safety instrumented system (SIS). Engineered for SIL 3-certified safety applications requiring long-term stable output states, it features a fault-tolerant quadruplicated output switch design with voltage/current loopback diagnostics to validate output integrity, field circuit health, and load presence. Optimized for 120 VDC industrial loads, the 3623T delivers fail-safe, supervised outputs to actuate critical field devices (emergency shutdown valves, solenoid valves, alarm systems) in hazardous environments. It complies with IEC 61508 SIL 3, FM, CSA, and ATEX standards, supports hot-swappable maintenance and hot-spare redundancy, and incorporates channel-level isolation to ensure stable operation in electrically noisy settings, making it an essential component for mission-critical safety interlock systems.

Key Functions

The TRICONEX 3623T module converts digital safety logic signals from the Tricon SIS controller into supervised 120 VDC outputs, with continuous diagnostics to prevent undetected failures. It provides 16 commoned channels with a fully fault-tolerant quadruplicated output switch architecture, ensuring reliable signal delivery even if a single switch component fails. Voltage and current loopback circuits enable real-time monitoring of output switches, field wiring, and load status, detecting faults such as power loss, fuse blow, load open/short, and field voltage anomalies without disrupting normal operation. The module supports hot-swappable replacement and hot-spare redundancy, maximizes system uptime, and features LED status indicators for quick channel-level fault troubleshooting. It requires an external termination panel (ETP) for field wiring and backplane integration.

Application Scenarios

The TRICONEX 3623T supervised digital output module is deployed exclusively in safety-critical applications requiring SIL 3 certification, fault tolerance, and continuous output supervision. In oil & gas facilities (offshore platforms, refineries, FPSOs), it triggers emergency shutdown (ESD) valves, fire suppression systems, and gas detection alarms in response to abnormal pressure/temperature readings. For chemical and petrochemical plants, it controls reactor isolation valves, emergency vent systems, and toxic material shutoff valves to mitigate explosion or leakage risks. In power generation (thermal, nuclear, renewable), it actuates turbine emergency stop systems, boiler safety valves, and cooling system shutdown mechanisms during critical faults. The module is also used in pharmaceutical manufacturing for batch process safety interlocks, mining operations for hoist/conveyor emergency stops, and water/wastewater treatment plants for chemical dosing shutdown systems—all scenarios where undetected output failures could result in human harm, environmental damage, or catastrophic equipment loss.
