Introduction
Warner Electric’s CBC-500 and CBC-550 series clutch/
brake controls are compact units designed for operation
with Warner Electric 90VDC and 24VDC clutches and
brakes, includ-ing failsafe units . Dual channel torque
adjust-ment is provided via on-board potentiometers for
soft starts and stops as well as accurate release points
for failsafe designs . These con-trols can operate with
each channel either in dual or single mode . Dual or single
mode is con-trolled via an on board jumper for use in a
vari-ety of applications . A transformer is provided on the
CBC-550 series controls, extending the input AC voltage
range . Four models are available:
CBC-500-90
120 VAC input
CBC-500-24
24-30 VAC or VDC input
CBC-550-90
120/220/240/380/480 VAC input
CBC-550-24
120/220/240/380/480 VAC input
Three optically isolated inputs provide full flexi-bility
in interfacing customer supplied switching schemes .
Internal circuitry provides suppression of transients
during decay of the magnetic field to assure rapid cycle
rates . Two LED indicators are provided on the control
board for channel 1 and channel 2 indication .
