Description
Product Overview
The DO 3401 Digital Output Module from Triconex delivers fault-tolerant control for safety instrumented systems. Designed for Tricon Systems, this 16-channel module supports emergency shutdown and process safety applications with SIL3 certification.
Each channel in the DO 3401 features three independent output circuits, enabling two-out-of-three voting logic for maximum reliability. This architecture eliminates single points of failure and ensures continuous operation even during component faults.
The module outputs 24VDC per channel, suitable for industrial actuators like solenoid valves and motor contactors. Its hot-swappable design allows technicians to replace the unit without halting operations, minimizing downtime in critical environments.
