VIPA 231-1BD53 SM 231 AI 4x16Bit Analog Input Module

VIPA 231-1BD53 SM 231 AI is a 4-channel analog input module for VIPA PLC systems, delivering 16-bit precision for real-time acquisition and processing of analog signals from temperature, pressure, flow, and level transmitters. Built for industrial automation, it is designed for control cabinet installation as part of a modular VIPA architecture, offering industrial-grade construction and continuous-duty operation in process plants, manufacturing lines, water treatment facilities, chemical processing, HVAC, and energy-management applications. Each of the four inputs supports standard industrial sensors and transmitters, enabling deterministic sampling and conversion to digital values that the PLC can use for monitoring and control. The 231-1BD53 is compatible with VIPA PLC systems and serves tasks such as system expansion, retrofit projects, and new automation installations; common replacements include VIPA 231-1BD52, Siemens SM331, and Allen-Bradley 1769-IF4. Its 4x16-bit resolution supports precise measurement of process variables, enabling accurate trend analysis and reliable control decisions in demanding environments.
