July 3, 2014 – Phoenix Contact says PLC Logic, the company’s programmable logic relay system, combines the strengths of an established relay technology with logic functions in a single package. The system, suited for small automation tasks, has a modular design, features plug-in relays and enables flexible assembly, depending on the switching task. The system consists of logic modules, the PLC-Interface relay system, and the Logic+ software that requires no previous experience in this area. To start up the system, the logic modules are plugged into eight relay modules. A compact, 50-mm-wide logic module can process 16 input/output signals. The base module can be expanded with up to two add-on modules for more complex applications, making it possible to process up to 48 input/output signals.
