AI825 - I/O AI825 3BSE036456R1 Modules - System 800xA hardware selector ABB
The AI825 Analog Input Module has 4 individually galvanic isolated, bipolar current/voltage inputs. Each channel can be either a voltage or current input.
The module has a direct current input that withstand up to 6.3 V and a over voltage protected current input that withstand up to +30 V d.c. The current is limited by a PTC resistor.
Power to the input stages is converted from the 24 V on the ModuleBus.
