The TRICONEX 2401 DO2401 32 Channel Output Module is the Model 2401 digital output baseplate of the Triconex/Trident TMR safety system — the mounting baseplate for a 16-point digital output module, providing backplane connectivity and field-wiring termination for DO channels driving solenoids, relays and motor starters. Per the official Trident Planning and Installation Manual, it includes dual field-power inputs (PS1/PS2), load connections, voltage loopback and a detector function.
Key Features
- Digital output (DO) baseplate for Triconex / Trident TMR safety systems (Model 2401)
