Clutch/Brake Controller Hardware
Chapter 3
3Ć6
Although this manual describes a single clutch/brake controller, you may
connect your PLC to multiple controllers, each controlling a separate
press. Each clutch/brake controller uses two remote I/O racks for chassis
A and B. For example, since a PLC-3 controller can support as many as
32 I/O racks, you may connect it to as many as 15 clutch/brake controllers
with two additional I/O racks for modules in chassis C.
You can operate your press using up to four operator stations and an
optional control panel. Installations vary according to the type of
mechanical press and its application requirements. The number of
stations, control switches contained in each, and the control panel could
be as follows:
