PLC Systems

PLC systems consist of programmable logic controllers, which read input signals and drive outputs according to a user program, together with their expansion modules and accessories. Replacing relay control circuits, they combine sequencing, timing and counting tasks in a single program in machine, conveyor, packaging line and pump station automation. In addition to the PLC CPU, compact PLC with display, positioning module and PLC accessories subgroups, the category lists the Schneider Electric Zelio and Modicon M221 series, ABB AC500 processors and safety PLC modules, Delta DVP PLCs and GEMO smart relays. Select the number of digital and analog inputs and outputs, the output type (relay or transistor), the communication ports and the program capacity according to the machine's signal list, and the supply voltage according to your panel. Expansion modules, connection bases and memory cards are series-specific; verify CPU compatibility from the manufacturer's data. For safety PLCs, the SIL level is stated in the product data; the required level is determined by the machine's risk assessment.
