PRODUCT INFORMATION
Product Overview
The ABB AI845 3BSE023675R1 is an S800 I/O Analog Input Module. This unit provides eight single-ended input channels for standard field process transmitters. It accepts current signals of 0 to 20 mA or 4 to 20 mA. The module also processes voltage inputs ranging from 0 to 5 V or 1 to 5 V.
Each channel features current-limited transmitter power distribution directly from the module. The hardware provides 12-bit analog-to-digital conversion resolution and 0.1 percent accuracy. It incorporates HART pass-through communication for intelligent field device diagnostics. The unit operates with a 50 V rated isolation barrier.
