The DGH D5200M Modbus ADC series four channel current input product line converts up to four 4-20mA analog DC current signals to digital information, linearizes the digital data and communicates the values to a host computer or PLC.
The data values are transmitted to a host computer via an RS-232 or RS-485 serial communications link using either the DGH ASCII protocol or Modbus RTU binary protocol. The protocol is user-selectable.
Because the Modbus RTU protocol does not support echoing, the RS232 versions of D5200M series are limited to one ADC per serial port. Applications requiring more than four ADC channels should use RS485.
The D5200M series modules can also be mounted on a DIN-Rail using the MK-1 mounting kit.
