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:
Transformer Input Voltage 9/440 Resolver- based Input Voltage Range
(Transformer Output)
Number of Axis Modules
125/240 V AC
(85-265 V AC @50/60 Hz)
24V ac (19 -- 28V ac, single phase @50/60 Hz)
or

(85-265 V AC @50/60 Hz) or
24V dc (18.75 -- 31.25V)

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.
