The DGH analog input modules are complete data acquisition systems designed for use with personal computers, PLC’s, and other processor-based equipment. These modules provide a direct connection to a wide variety of industrial sensors including DC voltages, 4-20mA current loops, thermocouples, RTD probes, thermistors, load cells, frequency sources and more.
The modules contain an isolated analog input, perform all signal conditioning, high resolution A/D conversion, linearization, and scale the digital data values into engineering units. Data values are communicated to a host computer using either the DGH ASCII serial protocol, the Modbus RTU serial protocol or the Modbus TCP Ethernet protocol. Each module is available with a serial, USB or Ethernet interface.
