The MRxxxx series relay modules allow the direct switching of high power levels and can also be used in a variety of ways. The MR4107-1021-2245 relay module is used to connect an ohmic or inductive 3-phase AC load. ? The solid-state relay output is connected to the AC load via a hybrid B23 connector. The current carrying capacity per phase is 7?A. In addition, the MR4307-1031-2242 has an analog input on a separate M12 connector that can process RTDs and TCs for temperature measurement.
