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.
WM868-SI2 is a module type with transmitting power 10 mW and 2,2 Ah internal battery.
WM868-SI4-H is a module type with transmitting power 25 mW and 7 Ah internal battery.
Radio collection modules WM868-SA2 are designed to connect two meters (or measured sensors) with analogue output and output value range (4 ÷ 20) mA, or (0 ÷ 10) V. The analogue inputs are measured in preset intervals (measured status) and thanks to A/D convertor are sent to WM868-SJ-XX collection unit type, or via gateway WM868-RFU/RFE/RFG to central application.
Indoor thermometer WM868-TI2 and thermometer with hygrometer WM868-TI3
Those modules are designed to measure indoor temperature/ and humidity. Recommended measured range is 0 ÷ 70 °C. The modules are equipped by a thermometer/hygrometer chip integrated directly to Printed circuit board. Actual temperature/humidity are sent as a radio message, either upon request („Wake-On Radio“ system) or automatically in preset time interval.
Indoor thermometers WM868-TID.L a WM868-TID.A
WM868-TID.A modules (with removable AA batteries) a WM868-TID.L (with LCD display) are designed to measure indoor temperature/ and humidity. Recommended measured range is 0 ÷ 70 °C. The modules are equipped by a thermometer/hygrometer chip integrated directly to Printed circuit board. Actual temperature/humidity are sent as a radio message, either upon request („Wake-On Radio“ system) or automatically in preset time interval.
Thanks to special message („WOR-packet“) it is possible to switch modules into active mode and reach actual information about temperature. Such a function is suitable for WALK-BY systems, or to provide configuration or modules diagnostics.
Outdoor thermometer WM868-TE-H
WM868-SEA radio adapter for Sensus Residia water meters
WM868-MDA, MDB radio adapter for Maddalena ONE-TRP water meters
WM868-MDA a WM868-MDB are designed to be connected (as an integral part) to specific Water meters Maddalena. Modules are powered by internal battery with 5 years endurance when reading every 30 min. The longer transmitting period, the longer battery endurance (up to 10 years). Modules are equipped by „Wake-On-Radio“ system, suitable for WALK-BY way of reading.
The module WM868-MDA is designed for Maddalena TT-CD SD-RF Water meter. The module is not equipped with backward running detection, it is recommended to be used with Water meters with integrated check flap.
Modul WM868-MDB is designed for Maddalena TT-CD ONE TRP Water meter. The module is equipped with backward running detection.
Both modules are equipped with vibration protection in order to avoid false measuring.
WM868-PLE, PLEV, PLE-W radio adapter for gas meters Elster
WM868-PLEV module is designed to remote reading of ELSTER gas meters equipped with ENCODER type of output protocol. The module shape allows fixing directly on the meter. The module reads data in preset intervals and sends them regularly as radio messages. Reading interval set up and message sending period are independent. Messages with read data can be also sent based on demand with „Wake-On-Radio“ system, such a function is suitable mainly for walk-by systems. To „force“ message sending it is necessary to apply additional HW and SW equipment (the module WM868-RFU-H, PC/notebook, WACO Walk-By software). The WM868-PLEV module is equipped with coding system to transmit special commands to open/close valves. Such a system is functional only when the gas meter is connected via ENCODER Valve interface. Where WACO network available, the radio messages are transmitted via WM868-RFU (WACO USB GateWay), WM868-RFE (WACO Ethernet GateWay), or WM868-RFG (WACO GSM GateWay), where they are converted from radio format into communication via serial line (WM868-RFU), suitable for further PC work, or via PC network communication (WM868-RFE/RFG suitable for PC remote access.
