REGENT’S

ClutchBraker™

 CLUTCH/BRAKE CONTROL
ClutchBraker120 for 120 VAC Logic
ClutchBraker32 for DC Logic
ClutchBrakerV12 for external switch

Features:

  • Provides power directly to clutch/brake. No interfacing relays needed (less wiring).
  • Flexible, versatile control interface. PLC compatible.
  • Increases clutch/brake life with adjustable switching time delay.
  • Fast response time for high-speed machines.
  • Compact size. DIN rail or panel mount.
  • LED status indicator for each load.
  • Regent’s 5 Year “No-Questions-Asked” Warranty.

Ideal for:

  • Material handling
  • Indexing tables
  • Winding machines
  • Automatic cutoff
  • Conveyor control
  • Packaging machines
  • Film feed
  • Label feed
  • Alternate clutch/brake drive or twin
  • Clutch applications (2 speed and reversing)

 

The ClutchBraker is an all-solid-state power supply relay for 90 VDC magnetic clutches and brakes. Its advanced features offer the ability to operate clutches and brakes at very high speeds, with less mechanical wear.

Logic level input permits direct interface with PLC output modules, photoelectric controls, proximity sensors, contacts, transistors, etc.

Adjustable switching time delay lets you minimize overlap between the clutch and brake, which means longer mechanical life.

NOTE
1. Logic terminals 1,2 on the ClutchBraker120 and ClutchBraker32 are isolated. Terminal L2 and/or 2 may be grounded.
2. Logic terminals 1,2,3 on the ClutchBrakerV12 are not isolated and must not be grounded.
3. Load terminals A,B,C and terminal 3 are not isolated from line terminals L1,L2 and must not be connected to ground or the ground side of the line.
4. Do not place switches or mechanical contacts between clutch and brake and their terminals A,B,C. Opening these circuits while current is flowing may damage the control.

Clutch/Brake Control

OPERATION (refer to TIMING DIAGRAM)

ClutchBraker120 and ClutchBraker32

a. When power is applied to L1,L2 with no logic voltage present, the brake energizes.

b. When logic voltage is applied to 1,2 brake immediately de-energizes.  Clutch is energized following preset Switching Time Delay.

c. When logic voltage is removed, clutch de-energizes and, following Switching Time Delay, brake energizes.         

ClutchBrakerV12

Maintained 2-wire (1 SPST switch)

a. When power is applied to L1,L2 with 1,3 contacts open, brake energizes.

b. Maintained closure of 1,3 contacts causes brake to de-energize.  Clutch is energized following Switching Time Delay.

c. When 1,3 contacts open, clutch de-energizes and, following Switching Time Delay, brake energizes

Maintained 3-wire (1SPDT switch)

a. When power is applied to L1,L2 with 2,3 contacts closed, brake energizes.

b. When 2,3 contacts open and 1,3 contacts close, brake de- energizes.  Clutch is energized following Switching Time Delay.

c. When 1,3 contacts open and 2,3 contacts close, clutch de-energizes and, following Switching Time Delay, brake  energizes.

Momentary (2 SPST switches)

a. When power is applied to L1,L2 with 1,3 and 2,3 contacts open, brake energizes.

b. Momentary closure of 1,3 contacts causes brake to de-energize.  Clutch is energized following Switching Time Delay.

c. Momentary closure of 2,3 contacts causes clutch to de-energize.  Brake is energized following Switching Time Delay.

d. With 1,3 and 2,3 contacts closed, 1,3 contacts override and clutch energizes.

SWITCHING TIME DELAY

Regent’s ClutchBraker features adjustable Switching Time Delay.  Switching Time Delay is a delay between clutch turn-off and brake turn-on, and vice versa, to reduce overlap.  By adjusting this delay, you can obtain the fastest cycle time and the least wear on your mechanical system. 

If a clutch/brake switches too quickly, there may be mechanical overlap between the clutch and brake.  Switching time delay can reduce or eliminate this overlap increasing the useful life of the clutch and brake.

The ClutchBraker is ordinarily supplied with an 8.2 K ohm resistor providing 82 msec switching time delay (i.e. 1K = 10 msec).  Correct setting depends upon clutch/brake size, response time, and load inertia (see table below for sample values).  Flux rise time in clutch or brake coil is independent of Switching Time Delay.
