Datexel Signal Converter Current to RS485 Converter - DAT3017-I

8 Channels Input, Supports Modbus, Watch-Dog Alarm, UL/CE Mark – Italian Made

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 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.

COMMUNICATION PROTOCOLS

The DAT 3017-I 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.
