Triconex 3603B Digital Output Module
Product Overview
The Triconex 3603B is a high-integrity, thirty-two-point digital output module designed for the TMR (triple modular redundancy) Tricon control system. It converts logic commands from the Tricon CPU into discrete switching outputs, driving actuators, alarms, and interlocks with SIL-3 safety integrity. Its rugged construction and advanced diagnostics ensure reliable operation in critical process environments.

Applications
-
Emergency Shutdown: Drives solenoid valves and shutdown relays for safety systems.
-
Alarm and Indication: Activates beacon lights, horns, and annunciators in control rooms.
-
Interlock Control: Implements permissive logic for pumps, compressors, and turbine controls.
-
Batch Sequencing: Automates discrete processes in batch reactors and packaging lines.
-
Integration with SIS: Interfaces with safety instrumented systems requiring SIL-3 performance.
Advantages
-
High Safety Integrity (SIL-3)
Triple-modular redundancy architecture delivers failsafe operation meeting IEC 61508 standards. -
Robust Diagnostics
Continuous self-testing and point-level fault detection ensure rapid fault isolation and minimal downtime. -
Flexible Voltage Support
Wide DC output range (24–125 V) supports diverse actuator types without additional power modules. -
Hot-Swap Capability
Modules can be replaced online without compromising the integrity of the remaining rack. -
Compact Footprint
Fits standard 200 × 150 mm rack slots with shallow depth for tight cabinet spaces.
