Through its RS-485 serial input, it offers openness and compatibility with all Modbus-RTU equipment (sensors, radar, flow meters) present in these networks.
With DL4W OpenSensor HP it is possible to power 0V, 12V and 20V (maximum 0.8W), control up to 8 devices and read 14 registers.
In addition, the data logger has 2 digital inputs (DI) to read the indexes of the sectorization or interconnection meters, manage "round trip" type meters and signal the opening of the manhole cover. Its analog input (AI) allows you to, among other things, power and control a 4-20 mA pressure sensor.
