The WM868-SI4-H module is intended for remote reading of consumption meters (water meters, gas meters, electricity meters, calorimeters), which are equipped with a standard pulse output, commonly used in the field of energy and media consumption measurement (“SI” type output).
The WM868-SI4-H module is intended for remote reading of consumption meters (water meters, gas meters, electricity meters, calorimeters), which are equipped with a standard pulse output, commonly used in the field of energy and media consumption measurement (“SI” type output). The module has four SI type inputs to which four consumption meters can be connected, which can be of different types, with different units and conversion constants. The module continuously reads the pulses generated by the consumption meter into internal counters, on the basis of preset multiplication / division constants converts them to the required consumption units (m3, kWh, MJ…) and sends current data on the consumption meter plan in the form of radio messages, either on request (via the “Wake-On-Radio” system) or automatically at a set time interval. The message with the current elevation value of the consumption meter is of the “INFO” type and, in addition to the elevation data of the connected meters, it also contains the system time of the module, the battery voltage and the processor temperature.
The module can also be used to connect up to four status sensors (for example, protective and door contacts, flood sensors, fire detectors, etc.). In this mode, the module detects any change in the status of the connected sensor and immediately sends a status change message.
The transmitted messages are further transmitted via the WACO network to WM868-RFU (WACO USB Gateway), WM868-RFE (WACO Ethernet Gateway) or WM868-RFG (WACO GSM Gateway) communication gateways, where they are converted from radio format to communication format via serial line (WM868-RFU), suitable for processing by a local computer, or for communication format over a computer network (WM868-RFE / RFG), suitable for processing by a remote computer.
Alternatively, messages with consumption data can be transmitted to the so-called “collection unit” of the WACO system, which collects data from WM868-SI / SA / SISA and WM868-TI / TE modules in the WACO radio network, converting the collected data into standard M bus protocol messages -BUS and their further transmission in M-BUS format via the physical bus or in the virtual WACO bus.
The module with a transmitting power of 25 mW is powered by an internal battery with a capacity of 7 Ah, which allows it to work for more than 5 years with a reading period of 20 minutes and longer.
The WM868-SI4 / WM868-SI4-H module is equipped with a “Wake-On-Radio” system, which allows communication to be initiated on demand (outside the set interval). With a special radio message (“WOR-packet”), the module can be immediately activated to the active state and request current information about the survey. This mode can be used to obtain instantaneous consumption information using the walk-through reading method (WALK-BY system), or to perform remote diagnostics and configuration of the module via the radio network.
