ABB 3BSE008516R1 Analog Input Module 8 Channel

ABB AI810 (3BSE008516R1) Analog Input Module is an 8-channel PLC I/O device that converts and conditions analog input signals for controllers in industrial automation systems. It is commonly installed in PLC racks, drive control cabinets, and distributed automation architectures where precise analog input processing supports PID loops, sensor feedback, and real-time control. This model handles eight analog input channels and supports analog voltage and/or current signals, with channel count and input type determined by the specific configuration. Power is supplied from the control power bus, and the module interfaces via an industrial signal connector interface for panel or rack mounting. Applications span process automation environments such as manufacturing production lines, water and wastewater facilities, chemical plants, material handling systems, and energy management where reliable analog signal acquisition improves control accuracy and system responsiveness. Common replacements include ABB AI820, DI810, and AO810 modules.
