This NetControl model is equiped with 4 channels for counting of pulses from external devices for measurement of energy, flow (water, gas) and others, which has the industry standard >80ms pulse output (opto isolated). You must setup in NetControl's interface the transformation constant and its current display value. This way you get a copy of the measurement device's display in NetControl's interface which can be of course accessed any time remotely via Internet or local network.

Using the cloud platform additionally you get function for callculating the real cost of used energy (via user defined tariff plans), graphical reporting of energy consumption, archives. You can also define condtions based on the current energy consumptions that will execute user define actions (including alerts or actions).

In addition to the pulse counter channels you get two SPDT relay outputs (for up to 7A/220VAC).
