The pluggable and 6.2 mm small pl-c-interface relay and optocoupler product range from phoenix contact gmbh is expanded with the plc-s046 line. Interface elements are implemented where conventional relays and optocouplers cannot correctly shut off, because of noise voltage interference [caused by the control system] or a leakage of current. Effective filter switching reduces unwanted disturbances such as initiator leakage currents or noise voltage interference arising along longer control cables. This noticeable improves the switching behavior as well. The modules are designed for use with 120 v ac and 230 v ac power supplies and are available either using screw or spring cage technology. In particular, the plc relay and optocoupler range features savings on space, wiring and cost.
