Datexel DAT 3017-I Distributed I/O Module 8 Input Channel +/- 20mA RS485 MODBUS-RTU communication protocol


  • Field-Bus remote data acquisition
  • Modbus Slave device on RS-485
  • Modbus RTU/ Modbus ASCII protocol
  • 8 channels input up to ± 20 mA
  • Watch-Dog Alarm
  • Remotely Configurable
  • 2000 Vac 3-ways Galvanic Isolation
  • High Accuracy
  • UL / CE mark
  • DIN rail mounting in compliance with EN-50022


The device DAT 3017-I is able to acquire up to 8 analogue input signals. The data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network (RS-232 interface is available).

It is possible to connect on input current signals up to ± 20 mA. The device guarantees high accuracy and stable measure versus time and temperature. To ensure the plant safety, two Watch-Dog timer alarms are provided.

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 DAT 3017-I is in compliance with the Directive 2004/108/EC on the electromagnetic compatibility. The DAT 3017-I is in compliance with the Directive UL 61010-1 for US market and with the Directive CSA C22.2 No 61010-1 for the Canadian market.

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.
