TRICONEX 3401 Digital Output Module
Product Overview
The TRICONEX 3401 is a high-performance digital output module designed for Safety Instrumented Systems (SIS). It reliably sends discrete ON/OFF control signals from the Tricon controller to external field devices. Moreover, Triple Modular Redundancy (TMR) ensures fault-tolerant operation, maintaining continuous performance even under fault conditions. Its robust design withstands harsh industrial environments, making it suitable for emergency shutdown, fire & gas detection, turbine protection, and other safety-critical applications.
