ABB AI523 B4

ABB AI523 B4 is an S500 series 16-channel analog input module for ABB AC500 PLC automation systems. This 16-channel analog input module collects voltage, current and RTD signals from field sensors. The 16-channel analog input module supports 2/3-wire sensor wiring for flexible field connection. This 16-channel analog input module provides galvanic isolation to protect PLC main units from field interference.

This unit adopts high-precision signal sampling circuit to convert analog signals into digital data for PLC processing. The accurate signal sampling circuit achieves 12-bit plus sign resolution for measurement. The stable signal sampling circuit ensures reliable data acquisition in continuous industrial operation. The anti-noise signal sampling circuit suppresses electromagnetic disturbance in workshop sites.

ABB AI523 B4 is equipped with compact DIN rail mounting housing for quick installation inside control cabinets. The lightweight DIN rail mounting housing saves cabinet space for multi-module configuration. The sturdy DIN rail mounting housing withstands mechanical vibration in industrial environments. The ventilated DIN rail mounting housing prevents overheating during long-term running.

ABB AI523 B4 is widely used in chemical, energy, water treatment and marine automation control systems. It receives real-time process data including temperature, pressure and flow from field transmitters. Built-in LED status indicators help users quickly diagnose signal and fault status. Strict factory calibration and testing guarantee stable performance, it is a standard spare replacement part for ABB AC500 PLC system maintenance.
