Clutch/Brake Controller Hardware
This chapter will help you become familiar with the:
hardware components of your Allen-Bradley clutch/brake controller
functional relationships between your PLC and clutch/brake controller
interconnections between your PLC and clutch/brake controller
switch settings that configure your clutch/brake controller and establish
its rack addresses
For details on how to install the I/O chassis and modules, refer to the
installation publications that apply to your particular PLC. These
publications, listed in our Publications Index (publication SD-499),
discuss general layout rules, mounting dimensions, enclosure
considerations, module keying, and field wiring arm connection
technique.
Important: If you are using a large mechanical power press that
generates high levels of shock and vibration, we recommend that you
shock-mount each I/O chassis of your clutch/brake controller.
Important: Electrostatic discharge can damage integrated circuits or semi
conductors in the PM Module if you touch backplane connector pins or
internal components.
CAUTION: Rid yourself of charge before handling the module
by touching a grounded object.
Your clutch/brake controller consists of chassis A and B connected to
your PLC in a serial chain with remote I/O chassis, as shown in
Figure 3.1. Table 3.A. lists required and optional clutch/brake controller
hardware.
Chassis A and B are similar to remote I/O chassis. The major difference
is that the left-most slot of chassis A and B contains a clutch/brake
module. In contrast, the left-most slot of an I/O chassis contains an I/O
adapter module.
