The TRICONEX 2401 Replacement Digital Output Baseplate 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)
- Mounting baseplate for the 16-point DO module
- Dual field-power inputs (PS1/PS2) with load +/load − connections
- Voltage loopback and detector circuitry on the baseplate
- TMR architecture — interfaces the logic processors to field devices (solenoids, relays, motor starters)
- High-availability design for safety applications
- Related high-voltage variant: Model 2402 DO baseplate kit (relay-output ETP)
- Made in USA

Installation Notes
- Install the baseplate in the chassis slot; secure and connect the backplane/interconnect assembly.
- Wire field loads per the manual — observe field power PS1/PS2, load +/load − connections, and voltage loopback wiring.
- Check the detector / loopback function and output voting behavior during commissioning (TMR voting).
- Perform a DO loop test (de-energize-to-trip behavior) before returning the safety system to service.
Common Questions
What is the Model 2401? It is the digital output baseplate of the Triconex/Trident TMR safety system — the mounting baseplate for the 16-point DO module.
