ABB Ability™ System 800xA® hardware selector AI810

Features and benefits

• 8 channels for 0 .20 mA, 4 .20 mA, 0 .10 V or 2 .10 V d.c., single ended unipolar inputs

• 1 group of 8 channels isolated from ground

• 12 Bit resolution

• Input shunt resistors protected to 30 V by PTC resistor

• Analog inputs are short circuit secured to ZP or +24 V

• The input withstand HART communication.

The AI810 Analog Input Module has 8 channels. Each channel can be

either a voltage or current input. The current input is able to handle a

short circuit to the transmitter supply at least 30 V d.c without

damage. Current limiting is performed with a PTC resistor. The input

resistance of the current input is 250 ohm, PTC included.

The voltage input is able to withstand an over or undervoltage of at

least 30 V d.c. Input resistance is 290k ohm. Transmitter supply can

be connected to L1+, L1- and/or L2+, L2-.
