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.
Features and Benefits
4 channels individually galvanic isolated inputs for +20 mA, 0…20 mA, 4…20 mA, +10 V, 0…10 V, 2…10 V
