Modbus RTU 4 S0 inputs (DIN EN 62053-31)

The MR-SI4 Modbus RTU with 4 S0 inputs to DIN EN 62053-31 class A is suitable for counting S0 counter pulses. This allows very good integration of the module into an energy controlling system. In case of a power failure, the last counter readings are saved.
Modbus RTU, RS485 (two-wire bus), Supply voltage 20 V to 28 V AC/DC. Connection with spring clamp terminal blocks (push-in).
