N0VUSUN and Mitsubishi-D700-SC

[Doddy]

From the manual...



The outputs are opto-coupled, max 50mA. But that "max" is the maximum capability of the opto's transistor, not a guarantee of switching current (this might, probably will, be less).

I've googled the coil resistance of the MY4N-J and not getting anything sensible, similar OMRON power relays, 24V are around 650R so we can guess a switching current for reliable operation around 50mA. Whether you get that out of the NVEM will need you to experiment but I wouldn't bet the house on it working. If not, you'll need a current amplifier (a simple NPN transistor would do).

And you'd need to protect against the back-EMF from the relay, regardless.

If that makes sense then I won't bother with a diagram, but if a diag would help then let me know.
