Reliance 801418-14A Control Board Module

Reliance 801418-14A Control Board Module is a legacy replacement printed circuit board used in automation systems from Reliance, with cross-reference Reliance Electric 05433939 and 400172. The 801418-14A functions as the central control board within compatible drive and machine-control assemblies, handling the logic and signaling required to coordinate inputs and outputs in aging equipment. This module is identified by its part number to source a direct replacement for legacy systems that rely on this specific board, and it represents a compact, board-level solution rather than a full controller or power supply. As a control board component in older AB/Reliance Electric architectures, it interfaces with the backplane or carrier designed for this module and supports the role of translating control instructions into actionable I/O activity within the system. Common contexts for this part include industrial environments maintaining legacy automation lines where Reliance and Reliance Electric control boards were originally deployed, enabling continued operation of compatible equipment without a full system retrofit.
