Digital I/O module DAT3188-4

RS-485Modbusdistributed

The device DAT 3188/4 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; also, the outputs are protected against over currents and over temperature. 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 3188/4 is in compliance to the Directive 2004/108/EC on the electromagnetic compatibility. The DAT 3188/4 is housed in a rough self-extinguishing plastic enclosure of 17.5 mm thickness, suitable for EN 50022 standard DIN rail.
