Single-phase energy meter (10 A relay max 250 Vac), rTM Plug - German (European Schuko).

The wireless rTM Plug and Switch devices are part of the rTM system. These modules have the same features and are proposed with different electrical connections for adaptation to specific requirements. They comprise an energy meter and a control relay that can handle up to 2.5 kW single-phase electrical loads. These devices are installed between a normal 230 Vac power socket and the load being controlled. After having bound the device to a Carel wireless network, the relay can be controlled via a remote wireless connection in on/off mode, and instant power consumption of the connected appliance can be measured. A local button is available to override relay operation (on/off ) and monitor relay status. In the wireless network, these devices act as Routers, transferring wireless traffic between other compatible rTM SE system devices. They send the data wirelessly using the ZigBee™ communication protocol, communicating with the Access Point connected via a Modbus RTU RS485 serial line to a CAREL system. The devices are powered via the same 230 Vac socket they are plugged into.
