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.

In a Qbus system, motor control (for shutters, screens,…) can be done centrally (from the electrical distribution board) or decentrally (with a module on the bus closeby the motor).
