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, includ­ing failsafe units. Dual channel torque adjust­ment is provided via on-board potentiometers
for soft starts and stops as well as accurate
release points for failsafe designs. These con­trols can operate with each channel either in
dual or single mode. Dual or single mode is con­trolled via an on board jumper for use in a vari­ety 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 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 flexi­bility 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.
