Allen-Bradley SLC500 CPU's, PSU's, & I/O Chassis

The SLC500 family of PLC’s is built around two hardware options; a fixed controller which is expandable to 72 I/O using a two slot chassis, or a modular controller which is expandable to a maximum of 30 slots and 960 I/O using a choice of 6 CPU’s, 3 PSU’s, 4 sizes of I/O chassis and numerous digital, analogue, network and communications modules. The CPU has to be placed in the first slot, but all other modules can be placed in any slot. The programming software and most I/O modules are compatible with both options, giving users flexibility to configure solutions for a broad range of industrial control applications. CPU’s are supplied with manuals.
