If you are using the Compressor VI, then it's not required, however if you are using the Relay control direcly then it may be required, depending what mode you are using it in (forward, reverse or both).

However, if your relay is working at all, then it's probebly not required... it's a show stopper.

BTW.... Electromagnet..... ???? is this part of some active actuator?
Wouldn't this be dissalowed by <R53>.

<R53> Items specifically PROHIBITED from use on the ROBOT include:
A. Electric motors and/or servos different from, or in addition to, those in the KOP, with the exception of those specifically permitted by Rule <R52>.
B. Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic solenoid valves – the latter are permitted, the former are not).

One assumes that when you turn on/off your electromagnet, something on your robot moves... Isn't that the definition of an "electric solenoid"...

Not my call... just pointing it out.
