Power consumption of the electronics:
P = 0.7 W
El
Power consumption of a valve during activation (200 ms):
P = 0.9 W
Valve-ON
Power consumption of a valve after reduction:
P = 0.6 W
Valve
Power consumption of an optical position report:
P = 1.0 W
LED
Also, if several control head valves were to be opened simultaneously, the switch signal will be sent stag-
gered to the valves. Only one 0.9 W valve will ever be recorded.
Calculation examples:
Example 1:
3 valves are activated simultaneously, one position is reported (state for 200 ms):
P = P
Total El
3.8 W = 0.7 W
or
I = I
Total El
160 mA = 30 mA
Example 2:
3 valves have been activated simultaneously, one position is reported (persistent state):
P = P
Total El
3.5 W = 0.7 W
or
I = I
Total El
147 mA = 30 mA
When using an external initiator, its power requirement should be added.
