Datexel Isolated Module Isolated Modbus RTU 4-20mA Output - DAT10024

4 output channels, Galvanic Isolation, Modbus RTU/ Modbus ASCII protocol, CE mark - High Quality

The device DAT10024 drives up to 4 voltage signals up to 10V or current up to 20mA connected both in active and passive loop in digital format. The data are transmitted with MODBUS RTU / MODBUS ASCII protocol over the RS-485 network.

To ensure the plant safety, a Watch-Dog timer alarm is provided.

The output channels are configurable independently.

For each channel it is possible to set:

Type and output value;

preset of the value at the power up (Power-up) separated for output voltage and current;

preset of safety value (Safe) separated for output voltage and current.

It is possible to generate voltage signals up to 10V and current signals up to 20mA, both active or passive loops.

The device guarantees high accuracy and stable measure versus time and temperature.

The isolation between the parts of circuit removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.

The device is housed in a 6 module DIN rough self-extinguishing plastic box for mounting on EN-50022 standard DIN rail.

COMMUNICATION PROTOCOLS

The device is designed to work with the MODBUS RTU/MODBUS ASCII protocol: standard protocol in field-bus; allows to directly interface DAT10000 series devices to the larger part of PLCs and SCADA applications available on the market.
