PLC interface Weidmuller, Phoenix, Eurogi or other with terminal block or relay (classic or solid state). Like I just said I’m using Bus Bar System and compact motor starters Tesys U, 3RA6. Sometimes is enough to take a look on the constructors sites to find new solutions. The panel builders have to know all this new articles/components.
