Product Details:

TRICONEX 2401 also known as DO2401 is a 16-channel TMR digital output module built with triple modular redundancy (TMR) architecture for Triconex Tricon safety instrumented systems (SIS). This TMR safety I/O module receives digital safety commands from the Tricon main controller and converts the signals into standard 24VDC discrete output signals to drive solenoid valves, safety relays and on-site alarm actuators for safety interlock protection. The Tricon digital output module supports up to 2A output current per channel. Built-in periodic self-test diagnostics run every 500ms to detect open circuit, short circuit and internal hardware faults, and upload fault alarm messages to the Tricon engineering workstation in real time. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system. Front panel LED indicators display module PASS, FAULT and each channel output state for fast on-site troubleshooting. It adopts 2-out-of-3 voting logic to avoid single point of failure and fully meets SIL3 safety integrity level requirements. It can be installed in standard Tricon rack and cooperates with Tricon processor and other I/O modules. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX 2401 digital output module executes safety actions for ESD emergency shutdown, fire and gas protection and burner management systems.
