Original TRICONEX 2381 PI2381 Baseplate Spare
The Original TRICONEX 2381 PI2381 Baseplate Spare is the Model 2381 pulse input (PI) baseplate of the Triconex/Trident TMR safety system — the mounting baseplate for Tricon pulse input modules that provides backplane connectivity and field-wiring termination optimized for high-speed pulse-signal routing. Per the official Trident Planning and Installation Manual, it serves a 6-point PI module with dual field-power inputs (PS1/PS2), blown-fuse indication, shielding, and safety-resistor/configuration/sensor blocks.
Key Features
- Pulse input (PI) baseplate for Triconex / Trident TMR safety systems (Model 2381)
- Mounting baseplate for Tricon pulse input modules — backplane connectivity + field termination
- Supports 6-point PI module configuration
- Dual field-power inputs (PS1/PS2) with blown-fuse indicator
- Sensor block, configuration block and safety-resistor block for field wiring
- Differential and single-ended input signal modes supported
- Made in USA

- Origin: USA
Installation Notes
- Verify the baseplate part number (7400221-100) and kit contents against the Trident/Tricon system documentation before installation.
- Install the baseplate in the chassis slot; secure it and connect the backplane/interconnect assembly.
- Wire field connections per the manual — observe +24 V #1/#2, 24 V Return, shield and safety-resistor/config/sensor block wiring.
- Terminate all unused points to avoid false inputs.
- After installation, verify PI signal readings via the TMR diagnostics and perform a pulse-input loop test before returning the safety system to service.
Common Questions
What is the Model 2381? It is the pulse input (PI) baseplate of the Triconex/Trident TMR safety system — the mounting baseplate for Tricon pulse input modules, providing backplane connectivity and field-wiring termination.
What does the kit include? The baseplate kit comprises the I/O baseplate, interconnect assembly, slot cover and terminal cover (3000719-100 / 2921 / 2900 / 2901, per Triconex parts data).
What input modes does it support? Differential and single-ended pulse signals; differential inputs require 500 mV p-p (2 Hz–32 kHz) or 1 V p-p (0.5–2 Hz) per service data.
What is the field power arrangement? Dual field-power inputs PS1/PS2 (+24 V class) with a blown-fuse indicator.
