SS 3130 Distributed I/O module 4 digital inputs + 4 relay outputs on RS-485 network
General description
The device SS 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 SS 3130 is in compliance to the 89/336/EEC directive on the electromagnetic compatibility.
The SS 3130 is housed in a rough self-extinguishing plastic enclosure of 22.5 mm thickness, suitable for EN 50022 standard DIN rail.
