Hi,
I want to use two motorized valves to control incoming water, these valves operate at 24VDC W4.
When the valves opens or closes they draw 2 x 222 mA (working current) and 2 x 15 mA when they are not moved (Static current). I assume this means that the motors are only running when the valves opens or closes (and that there is no cause for concern see below).
My question is, should I run the motorized valves on a separate power supply or could LogicMachine5 Reactor IO, the relay and the valves share one if it is large enough?
My concern is that motors are inductive load and might introduce high-voltage spikes that may damage the LogicMachine5 or relay.
I am looking at the Finder 19.21.0.024.0000 relay, from Finders manual I can see that the relay has a built-in Protection and Inductive Circuit. Would adding a diode in proximity to the inductive load or suppression capacitors near the relay for additional protection make sense.
Is this a case of, better safe then sorry, and just use two 24VDC power supply's?
I found this line in LogicMachine5 Reactor IO manual;
”Binary input/Digital output 16 (Configurable). 380 mA continues current on output. Optoislated from KNX/EIB bus. Additional 24V power source is supported.”
I this used for separation of power, like the above problem?
But even with separated power supply one cable needs to connect the relay to LogicMachine5 binary output port so there will not be totally separate unless there is built-in separation in the LogicMachine5. Right or wrong?
Regards,
Joachim
