Datexel Remote I/O module Analog Output - DAT3024 ISO

4 Channels, Watch dog Alarm, CE mark, Highly Accurate – Italian Made

The DAT3024-ISO device generates 4 output analog signals from digital commands. The data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network. To ensure the plant safety, one 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 rough self-extinguishing plastic container which, thanks to its thin profile of 17.5mm only, allows a high density mounting on EN-50022 standard DIN rail.

COMMUNICATION PROTOCOLS

The DAT3024-ISO is designed to work with the MODBUS RTU/MODBUS ASCII protocol: standard protocol in field-bus; allows to directly interface DAT3000 series devices to the larger part of PLCs and SCADA applications available on the market.
