MODICON AS-B875-111 Analog Input Module

MODICON AS-B875-111 is a high-performance input module for Modicon 800 / 984 series PLC automation systems. This input module can be configured as 8 differential channels or 16 single-ended channels, supporting 4-20mA, 0-10V, ±10V multiple analog signal ranges. The input module adopts multi-range selection via DIP switch and anti-noise PCB layout. This input module supports stable continuous operation in chemical, power, water treatment and process manufacturing production lines.

It serves as a core signal collector to convert analog signals from transmitters, pressure, temperature and flow sensors into digital data for the PLC backplane. The signal collector supports configurable sampling averaging and over-range fault detection. This signal collector provides flexible wiring modes to adapt to different field sensor installation requirements. The signal collector is fully compatible with Modicon 984 rack-based PLC systems.

The unit delivers dependable analog signal acquisition for flow, pressure, temperature and liquid level monitoring loops. Accurate analog signal acquisition ensures reliable feedback for closed-loop process regulation. Stable analog signal acquisition suppresses field interference and improves measurement repeatability. The analog signal acquisition of this model meets strict industrial process automation standards.
