PRODUCT INFORMATION
Product Overview
The ABB AI825 3BSE036456R1 is an S800 I/O analog input module. It provides four individually isolated bipolar input channels for current and voltage signals. Each channel can be configured independently as either a voltage input or a current input. Power to the internal input stages is converted directly from the twenty-four volt ModuleBus line.
The module includes a direct current input that withstands voltages up to 6.3 volts DC. An overvoltage protected current input withstands up to positive thirty volts direct current. Internal PTC resistors limit input current to protect signal conditioning circuitry. The analog-to-digital converter delivers fourteen bits of resolution plus sign.
