Product Summary
Module WM868-SI4 / WM868-SI4-H is designed for data reading from the devices (meters – Water, gas, electricity, calorimeters) which are equipped by pulse outputs. Module has four internal digital inputs of SI type, to which you can connect up to four meters of a different type, different units or conversion constants. The module continuously reads pulses from the meters to an internal counter, and based on preset constants (multiplying/dividing) converts data to desired output unit of consumption (m3, kWh, MJ…). Actual data are sent as a radio message, either on demand (Wake-On-Radio), or automatically in a preset time interval. Available for SIGFOX, Narrow Band and 169 MHz as well, IP65, IP68, ATEX
