I have a series of contactors with 24V DC coils. These are being driven via an open collector output on a CNC controller (the spec sheet says it can handle max 50V and 500mA)
Is a flyback diode required across the contactor coil ?
The datasheet does not make any mention of a built in diode, so guessing an external one is required.
