Product Description

The WM868-SI2 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 two SI type inputs to which two 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 transmits 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 report with the current elevation value of the consumption meters contains, in addition to the elevation data, also the system time of the module, the battery voltage and the processor temperature.

The transmitted messages are further transmitted via the WACO network to communication gateways of the type WM868-RFU (WACO USB Gateway), WM868-RFE (WACO Ethernet Gateway), or WM868-RFG (WACO GSM Gateway), 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 is powered by an internal battery, which allows it to work for more than 5 years with a reading period of 20 minutes or longer.

The WM868-SI2 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.

WM868-SI2 is a variant of the module with a transmitting power of 10 mW and with an internal battery with a capacity of 2.2 Ah.
WM868-SI4-H is a variant of the module with a transmitting power of 25 mW and with an internal battery with a capacity of 7 Ah.
