Datexel DAT 3140 Data Acquisition Distributed I/O Module 4 digital inputs + 8 NPN outputs on RS-485 network


  • Field-Bus remote data acquisition
  • Modbus Slave device on RS-485
  • Modbus RTU/ Modbus ASCII protocol
  • 4 digital inputs
  • 8 digital outputs type NPN
  • Watch-Dog alarm
  • Galvanic isolation on all ways
  • High accuracy
  • UL / CE mark
  • In compliance to EN-50022 DIN rail mounting


The device DAT 3140 is able to acquire up to 4 digital inputs and to drive up to 8 transistor outputs. The data are transmitted with MODBUS RTU/ASCII protocol on RS-485 network. To assure safe operation of the system, the device is equipped with two Watch-Dog timers: in case of alarm, the outputs are forced automatically on the safe configuration. The galvanic isolation between inputs, outputs, power supply and RS-485 serial line cancels any ground-loop effect noise, allowing the use of the device in worst ambient conditions.

Distributed I/O module 4 digital inputs, 8 NPN output. Baud rate 38,4 Kbps. Max distance 1.2 Km. Power supply 10...30Vdc. Galvanic insulation 1000Vac 50Hz. , 1 min. (Input // output), 1000Vac 50Hz. 1 min. (Input // RS485, Input // Power supply, Output // RS485 , Output // Power Supply RS485 // Power Supply). RS485 MODBUS-RTUI communication protocol.
