Description
1. Product Description
The Triconex 2381 is a pulse input (PI) baseplate used in Trident safety and control systems. It provides field wiring connections and signal conditioning for compatible pulse input modules, supporting the acquisition of pulse signals from speed sensors, proximity probes, and other frequency-generating devices. Typical applications include turbine speed monitoring, rotational measurement, and industrial equipment protection. The baseplate works with the compatible Model 3381 pulse input module. Verify the complete assembly and system generation before ordering, as the 2381 is a baseplate rather than the pulse input electronics module itself.
