Product Description
The Honeywell 51452822-002 Control Board is designed to support reliable power and relay functions within Honeywell Experion PKS, TPS, and TDC 3000 systems. Its robust printed wiring assembly uses stable embedded logic to manage system signals, ensuring consistent operation in both legacy and upgraded installations. Moreover, the module’s rugged design protects sensitive circuits from electrical noise, vibration, and fluctuating plant conditions.
Engineers choose this board because it integrates smoothly with the system backplane while maintaining efficient communication between controllers and subsystems. Therefore, plants running UDC 2500 / 3200 controllers rely on its predictable behavior to maintain process continuity. In addition, the board’s engineered EMC suppression helps reduce disturbances that commonly affect control accuracy in industrial environments.
