Datexel DAT 3130 Distributed I/O Module 4 digital inputs + 4 relay outputs on RS-485 network


  • Field Bus data acquisition
  • Master/Slave communication on RS-485 network
  • MODBUS RTU/ASCII protocol
  • 4 digital inputs
  • 4 relay outputs (2 SPDT + 2 SPST)
  • Watch-Dog alarm
  • Four ways galvanic isolation 2000 Vac
  • High accuracy
  • EMC compliance – CE Mark
  • In compliance to EN-50022 DIN rail mounting


Distributed I/O Module 4 digital inputs, 2 SPDT relays outputs, 2 SPST N.O. relays outputs. Baud rate 38,4 Kbps, Max. distance 1,2 Km. Power supply 18...30Vdc. Galvanic insulation 2000Vac 50Hz., 1 min. RS485 MODBUS-RTU communication protocol.

The device DAT 3130 is able to acquire up to 4 digital inputs and to drive up to 4 relay 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 2000 Vac 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.

The DAT 3130 is in compliance to the 89/336/EEC directive on the electromagnetic compatibility.

The DAT 3130 is housed in a rough self-extinguishing plastic enclosure of 22.5 mm thickness, suitable for EN 50022 standard DIN rail.
