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.
