TRICONEX 2401 16-Channel Digital Output Module

TRICONEX 2401 is a 16-channel isolated digital output module for Tricon triple modular redundant safety instrumented system. It outputs safety on/off commands to field solenoid valves, relays and indicators for emergency shutdown and safety interlock control.

This module adopts TMR triple voting fault-tolerant architecture, with comprehensive channel diagnostic and line monitoring functions. It supports online hot swap without stopping the SIS system, widely used as spare replacement for petrochemical, power and chemical safety control cabinet maintenance and renovation projects.
