I/O SYSTEMS – S800 I/O – AI801

The AI801 Analog Input Module has 8 channels for 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.

Features and Benefits

  • 8 channels for 0…20 mA, 4…20 mA 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
  • Process and power connections via detachable connectors
