The AI825 analog input module has 4 electrically isolated bipolar current/voltage inputs. Each channel can be a voltage input or a current input.

The module has DC inputs that can withstand up to 6.3V and overvoltage protection current inputs that can withstand up to +30 V DC. The current is limited by a PTC resistor.

The power of the input stage is converted from 24 V on the ModuleBus.
