Datexel Isolated Module Digital Input Output Module on MODBUS RS485 - DAT3140

4 digital inputs, 8 digital outputs type NPN, Watch-Dog alarm, DIN rail mounting, UL / CE mark - High Quality

The device DAT 3140 is able to acquire up to 4 digital inputs and to drive up to 8 transistor outputs type NPN. The data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network.

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 3140 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 DAT3140 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.
