Features and benefits

• 4 channels individualy galvanic isolated inputs for +20 mA, 0 .20 mA, 4 .20 mA, +10 V, 0 .10 V, 2 .10 V

• 14 Bit resolution plus sign

• Input shunt resistors protected to 30 V d.c.

• The input withstands HART communication

The AI825 Analog Input Module has 4 individualy 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.
