MODBUS output signal converter: DT1104 UI ​​RS4

DT1104-UI-RS4-galvanic-isolator

Outstanding accuracy, with lower system cost

Preserving accuracy and optimizing costs is a constant challenge when designing industrial automation systems.
The DT1104 UI ​​RS4 MODBUS output galvanic isolator offers an effective, direct solution to these tasks.
The device receives analog signals from field transmitters, then converts them directly into digital format and transmits them to the signal processing unit (PLC, DCS) via an RS485 line (with MODBUS RTU/ASCII slave protocol).

Generation Change in AC Transmitters

DT1612 I AC-transmitter

The newly developed DT1612 I AC transmitter replaces the DT1600 I product family

During the design of the new device, our developers utilized the manufacturing experiences of the previous model, as well as user feedback.
One of the goals was to reduce the number of the previous 12 model variants. This has been achieved, as the two variants of the new DT1612 I fully replace the earlier ones.
Another goal was to increase the directly connectable input current. In the new device, this is 10 AAC, which eliminates the need for an external current transformer in many applications.

4 functions in one device

The DATCON DT1122 dual output galvanic isolator implements four functions in one device:

  • signal distribution (splitter function): transmits one input signal to two outputs
  • 4-way galvanic isolation
  • signal conversion: 0-20 mA / 4-20 mA / 0-10 V / 2-10 V (in any combination)
  • 20 V transmitter power supply at the input
