Productivity2000 PLC bases provide a means of housing and connecting the installed controller module, power supply, and selected I/O modules. These modular bases are available with up to 15 slots for I/O modules, and support both DIN-rail and flush-mount options.
With a PLC system, there are different options for connecting I/O modules to the CPU. Some systems have a fixed style where the CPU comes with a fixed set of I/O points. There are stackable styles where the CPU and I/O modules are separate but come with connectors built in that are used to attach the components together. Another option with PLC hardware is the modular base configuration. With this style of PLC, a separate base unit that holds the modular components is needed. Each module will seat into a slot on the base unit that is used to connect the module to the backplane already installed in the base. These bases may be available with different numbers of slots and some with power supplies built in. Typically, the first two leftmost slots are dedicated for the power supply and CPU.
The Productivity2000 PLC system utilizes a modular base that houses a power supply, CPU or remote I/O module, and connects the I/O modules to the CPU. With this modular base configuration, Productivity2000 I/O is easy to install and modify if needed. Simply slide the I/O module in or out of the base, and once installed, use the locking tabs to secure. Many modules can be hot swapped if required, meaning the module can be swapped with the PLC powered and with no interruption to the control process.
