Compact PLC – The open and closed-loop control system

Compact PLCs are all-in-one devices that, even in their basic version are equipped with a comprehensive set of hardware and software functions and thus suitable for use in many control, regulating and measuring applications. Where the integrated functions do not suffice, the devices can be simply expanded either locally or via network.

The range includes:

• Compact PLC – PS4
• LE4 – local expansion units
• EM4 – distributed expansion units.

All the compact PLC are networkable and programmable via integrated fieldbus. The programming software applicable to all is Sucosoft S40, an easy-to-use programming package to IEC 61131-3.
