General Description
The SS 3130 device can receive up to 4 digital inputs and control up to 4 relay outputs. Data is transmitted via MODBUS RTU/ASCII protocol to the RS-485 network.
To ensure safe system operation, the device is equipped with two Watch-Dog timers: in the event of an alarm, the outputs are automatically forced to a safe configuration.
The 2000 Vac galvanic isolation between inputs, outputs, power supply and RS-485 serial line cancels any ground-effect noise, allowing the device to be used in the worst ambient conditions.
The SS 3130 complies with the 89/336/EEC directive on electromagnetic compatibility.
The SS 3130 is housed in a rugged self-extinguishing plastic enclosure 22.5 mm thick, suitable for the standard EN 50022 DIN rail.
