Allen-Bradley 1201-HASI Product Description

Allen-Bradley 1201-HASI is a legacy high-density analog input module, belonging to Rockwell 1201 series industrial signal acquisition hardware. It collects multi-channel analog signals from field transmitters and sensors, converts analog 4-20mA / ±10V signals into digital data and transmits to the host controller. It is widely used in factory automation, process control and CNC equipment for continuous analog parameter monitoring. This module is stocked as fully tested surplus spare part for legacy PLC system maintenance and replacement.
