Switch Energy Meter


The wall-mounted ZR-SWITCH-M device is part of the ZB-Connection range. It includes a meter for electric energy and a relay to switch on and switch off loads up to 2,5 kW.


The ZR-SWITCH-M device is mounted to the wall and is connected to an equipment directly or through a socket or a splitter. Once attached to a wireless ZigBee ZB-Connection network you can remotely switch on and switch off the device and always remotely measure the instant active power and the energy spent. Moreover is available stand-by killer and override button functions. You can set a power limit under which the device is meant to be in stand-by killer mode and so can be automatically turned off. With the override button the user can override the last command from the Gateway. Such tasks are carried out after simple Modbus commands sent to ZB-Connection network that transform them in wireless commands.

The device is continuously supplied by a 230 Vca output, so it can also work as a repeater or a “father” device for battery supplied sensors.
