PLCs, Power Supplies & Others

The Triconex 2361 functions as a dedicated processor power module for Triconex safety instrumented systems. This module provides regulated DC power specifically for main processor modules in the chassis. Engineers use it to ensure reliable power delivery to the triple modular redundant processors. The 2361 maintains stable voltage outputs critical for safety system operation. Its robust design meets the stringent requirements of SIL 3 applications.

Technical Specifications

Power Delivery and Regulation

The 2361 delivers 15 Amps of continuous +5 Vdc power to processor modules. This capacity supports the power requirements of triple modular redundant processors simultaneously. Tight line and load regulation maintain stable voltage despite input variations. Output ripple remains below 50 mV for clean power to sensitive logic circuits. The module ensures processors receive consistent power for fault-free operation.

Input Flexibility and Isolation

Triconex 2361 accepts either 115 Vac or 230 Vac input with simple selector switching. This flexibility suits global installations with different utility voltages. The module provides 1500 Vac isolation between input and output circuits. Isolation protects processor electronics from line transients and noise. Engineers deploy the same module worldwide without modification.

Energy Storage and Hold-up

Large filter capacitors store energy for hold-up during brief input interruptions. The 2361 maintains output for at least 20 ms after input power loss. This hold-up time allows processors to continue operation through power dips. Critical safety functions remain active during momentary disturbances. The energy storage also filters input ripple for clean DC output.

Protection and Reliability Features

The 2361 incorporates comprehensive protection circuits for system safety. Overcurrent protection limits output during fault conditions automatically. Overvoltage protection prevents excessive voltage from reaching processor modules. Short circuit protection immediately reduces output during direct shorts. Thermal shutdown activates if internal temperatures exceed safe limits. These features ensure long-term reliability in continuous duty applications.

Physical Design and Integration

The 2361 mounts in dedicated power supply slots within Triconex main chassis. Its compact size leaves space for additional system modules. LED indicators show input power, output power, and fault status clearly. Terminal blocks accommodate AC input wiring for field connections. Backplane connectors deliver DC power directly to processor slots. Similar to protection devices like the RMS TSG TZ C Static Trip unit, this module ensures system integrity.

Application in Safety Systems

Engineers use the 2361 to power main processors in Triconex safety instrumented systems. Multiple modules can configure for redundant power in high-availability applications. The module supports continuous operation in emergency shutdown and fire and gas systems. Its reliable performance proves essential for SIL 3 certified applications. Process industries depend on this power module for critical safety functions.
