2- Inputs and outputs
2�3�5 Analog outputs
The analog outputs supply voltage to earth (GND). Up to 2 mA load for each output. The outputs
are short circuit proof. If the same transformer is used to supply the WMPro and actuators, be careful
with phase and neutral throughout the system. For the cable dimension, follow the manufacturer's
recommendations .
2�3�4 Digital inputs
Digital inputs have an internal 12 V supply via a resistor, and the input must be connected to earth
(GND) with a dry contact output. Equipment with open collector or open drain outputs can also
be used, but remember that the WMPro GND is connected to the equipment ground – which may
cause problems in some situations.
