Introduction
The Warner Electric CBC-400 and CBC-450 series
clutch/brake controls are compact units designed
for operation with any of the Warner Electric
24VDC and 90VDC clutches and brakes. These
controls supply full nominal voltage to the
magnets for on-off applications.
These controls can be configured via jumper to
operate alternately between channel 1 and
channel 2 or simultaneously both channels on or
off at the same time. These controls can operate a
single clutch or brake, two clutches, two brakes
or a combination clutch/brake.
Solid state optically isolated switching allows for
maximum flexibility in interfacing to customers’
switching requirements. This allows for using
either the internal supply voltage or on external
supply voltage for full isolation. Because the
inputs are optically coupled, switching can be
done by switches, relays or solid state devices
that can be sinking (NPN) or sourcing (PNP).
Additionally, the control has an input line fuse to
provide protection in the event of a short on the
output or overloads. Internal circuitry provides
suppression of turn-off transients when the
magnets are switched to aid in the decay of the

provide a visual indication as to which output
is active.
Transformer input is provided on the CBC-450
series controls extending the operating AC input
