Question
What is the maximum distance for operating MY4 DC24V General-purpose Relays?
Answer
The distance depends on the type and installation conditions of the cable. Both ends of the Relays coil must measure at least 90% of the rated coil voltage to operate without problems. It is essential to check this beforehand.
