Can I use your hour meter to count twistlock operations? I have a PLC that could send a pulse to your meter. I read on your spec sheet that the resolution for your meter is 1/100 hour. So I guess if I turn my output on for 36 seconds per twistlock operation, the hour meter could read the twistlock counts. My only concern would be how long the meter would last since I am not sure what the input circuitry is.
