Hello, partners. I'm a newb here, so if you have ever seen me at other unrelated message boards, you can tell me where and who were you freely.
Regarding this thread, I have problems with this:
I have an energy meter, ES210. This device has two digital outputs that feed two optocouplers (one each, I'd only use one). You can connect a +40VDC MAX power source to the common collector and can have a maximum current of 150mA. However, I need also to connect either a 12VDC or a 24VDC relay to it in order to connect a 110VAC strobe light to the relay's power contacts.
What should I do? Use a 12VDC power source connected straight to the collector and connect the relay as a resistor at the emissor? I fear of damaging the output. And using a 24VDC or 40VDC at the emissor creates the need of having a voltage divider with two resistors at the emissor, but since I don't know which relay should I use, I don't know what would the resistive value be and therefore any resistor I connect it in parallel with would be unreliable.
What do you suggest?
Any ideas will be more clever than mine. Thanks and see you.
