General Description

The Modbus to 4-20mA Output converter DAT3022 is a 2 channel Current or Voltage output module. The DAT3022 converters Modbus into 4-20 mA, 0-20mA or 0-10V. The DAT3022 Current and Voltage output is Isolated from the Power Supply and the Modbus signal. The Slew rate is adjustable. The DAT3022 is also available in the RS232 ASCII format.
