Clutch/Brake Controller Hardware

In addition to chassis A and B, you must connect your PLC to at least one
local or remote I/O chassis, chassis C. You need two, three, or four inputs
at a local or remote I/O chassis.
Important: You must use 2-slot addressing and 8-point (single-density)
I/O modules.
Typical twinaxial cable connections of your clutch/brake controller are
shown in Figure 3.2. Connect your clutch/brake controller to your PLC as
part of its remote I/O distribution network. Use Twinaxial Cable (cat.no.
1770-CD) and Terminators (cat. no. 1770-XT).
Connect chassis A next to chassis B in the serial chain as shown in
Figure 3.2. You may connect one or more remote I/O chassis in the same
serial chain. Also, you may connect remote I/O chassis to other
distribution channels at the I/O scanner module of your PLC.
Connect four Terminator Resistors (cat. No. 1770-XT) as shown in
Figure 3.2. Connect one at:
the scanner module
the last chassis, whether it is a clutch/brake chassis or a remote I/O
chassis
each end of the cable that connects chassis A and B at terminals 7, 8
and 9 of the 1771-PM module field wiring arms
For more information on how to connect remote I/O channels, refer to the
installation publications that apply to your particular PLC. Also refer to
Product Data of the Remote I/O Adapter Module. These publications are
listed in our Publications Index (publication SD499)
