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.
