Module which counts and processes pulses received from a pulse meter. Any pulse meter can be connected to the ECM04 as long as the contacts are potential-free. The ECM04 can receive a pulse every 250ms. Alarms can be triggered based on a set number of pulses, for example to receive green energy certificates every kW generated by solar panels.

Via the relay modules, outputs can be switched. A relay module has no specific function but can handle any switch functions: monostable (eg a doorbell), bistable (on / off), timer, interval, thermostat output. Some relays can also control motors of blinds, curtains, gates.

The range of Qbus dimmermodules goes from standard dimmers to dim halogene or incandescent lights over universal dimmers for any load to 0/1-10V dimmers to dim analogue circuits or energy savings lamps.
