Products Description
ABB AI810 3BSE008516R1 Analog Input Module
The ABB AI810 with part number 3BSE008516R1 is an 8-channel analog input module belonging to ABB S800 I/O series for AC800M DCS system. It collects standard 4-20mA analog signals from field transmitters and converts analog measurements into digital data for the DCS controller to realize process monitoring.

This rack plug-in module supports channel-level isolation and fault diagnosis. It communicates with the AC800M controller via Profibus DP fieldbus. Front panel LED lights indicate power, communication and channel status. Hot swap is supported for online replacement. As aftermarket spare parts, it is widely used for maintenance, replacement and retrofit of power, chemical and pulp & paper DCS systems.

FAQ
- Q: Can ABB AI810 3BSE008516R1 work independently without S800 rack and AC800M controller?
A: It needs to be installed in S800 I/O rack and communicate with AC800M controller, cannot run as standalone hardware. - Q: What are typical module failure symptoms?
A: Communication loss, partial channel reading deviation or no signal, module fault LED on. - Q: How to complete commissioning and diagnosis?
A: Check rack power supply and field transmitter wiring; use DCS software to view channel values, diagnostic logs and fault alarms.
