VIPA 231-1BD53 Digital Input Module

The VIPA 231-1BD53 SM 231 analog input module provides 4 channels of 16-bit analog signal acquisition for VIPA PLC systems, enabling precise monitoring of sensors and transmitters in process control equipment and manufacturing lines. Manufactured by VIPA (Yaskawa VIPA), part number 231-1BD53, this module is part of the SM 231 series and is designed for continuous-duty operation in industrial control cabinets. It supports analog sensors and transmitters for temperature, pressure, flow, and level, feeding real-time data to the controller for monitoring and control within a modular PLC architecture. Common applications include process control machinery, water treatment facilities, chemical processing plants, manufacturing lines, HVAC control systems, and energy management installations where accurate analog data is essential. Common replacements include VIPA 231-1BD52, Siemens SM331 Analog Input Module, and Allen-Bradley 1769-IF4.
