Allen-Bradley 0-51831-2 Current Voltage Transducer Card Module

The RELIANCE ELECTRIC 0-51831-2 CVTC (Current Voltage Transducer Card) module is an industrial printed circuit board used in Reliance Electric motor drive and automation systems to measure and condition armature current and voltage feedback signals. Designed for DC drive systems and process control equipment, it provides scaled feedback signals necessary for accurate motor speed and torque regulation. The module includes dedicated terminals for COM, COMV, ARM CURRENT FB, 500V, 240V, 180V, 100MV, and COM, and accepts armature current and voltage feedback input signals. It is part of the Reliance Drive Boards family, with part number 0-51831-2 (alternate 0518312), board type Industrial PCB, mounting as chassis/rack mounted, and construction as a multi-layer PCB. It is compatible with Reliance Electric DC Drives and Control Systems for applications in manufacturing, motion control, and process automation, commonly used for repair, retrofit, or replacement of failed control electronics in legacy Reliance installations. Repair availability is Yes, and this is a legacy OEM replacement component available through surplus suppliers.
