24 Volt logic power is supplied to the 9/440 resolver–based control to run
the processor board and axis module logic boards. The 24 volts are
provided from a customer supplied transformer. Specifications for this
supply are:

On/Off connections are made through the Allen-Bradley On/Off Control
assembly (8520-OFC). This assembly allows connection to the standard
MTB panel on/off switch and should be used to supply power to your 24 V
transformer.
