TRICONEX DO3401 16-Channel Digital Output Module
TRICONEX DO3401 is a 16-channel isolated digital output module for Trident triple modular redundant safety instrumented system. It receives safety interlock commands and sends 24V DC discrete on/off signals to field solenoid valves, safety relays and status indicators for emergency trip control.
This module adopts TMR triple voting fault-tolerant solid-state output design, with channel-level overcurrent and short-circuit protection. It supports comprehensive wiring diagnostics and online hot swap without shutting down SIS system, widely used as spare replacement for petrochemical, power and chemical safety control cabinet maintenance and retrofit projects.
