ADI-524

Opto-isolated 4-20mA to Modbus and USB

  • Four opto-isolated analog inputs
  • 16 bit Sigma Delta converter
  • Additional USB port for direct connection to a computer

The ADI-524 is 4-20mA analog input interface converter to Modbus RTU over RS485 or over USB. It has 4 opto-isolated analogue inputs and RS485/USB output. Extra isolated 24V power supply for 4-20mA sensor/devices and DIP switch for baud-rate and address setting.
USB port make this device perfect to use with industrial computers and gateways with USB port.
It can be mounted on standard DIN rail or by using clamps.

Applications

  • Temperature sensors, laser distance sensors, other industrial sensors
  • Industry, infrastructure and energy and water supply systems
