I have a commercial machine that has the following voltages available. 480 3 phase (main) 220V AC and 24V DC. I need to connect a 24V DC hour meter that runs only when the main motor is running. Normally I would connect the hour meter to the control voltage pulling down the contactor for the main motor. However this machine uses a motor drive (inverter) to control the main motor.
I am looking for a way to us a N.O. momentary switch (added to the current start Button) to latch a circuit that uses the available 24V DC to power a 24V DC hour meter. And then a N.C. momentary switch (added to the current stop Button) to stop the hour meter.
an example circuit would be great. Is there an electronic way to do this. Most examples of a latching relay us a relay with a 12V coil.
Thanks
