KM2642, KM2652 | 2-channel relay module 230 V AC, 6 A, manual/automatic operation

The digital KM2642 and KM2652 output terminals have two independent relay change-over contacts, which can be used for switching mains current consumers. For each channel a switch enables selection between automatic, manual on, manual off. In automatic mode the logical state of an output bit switches the relay. For manual mode a 24 V supply is required for the Bus Coupler. The output state – for KM2652 also the state of the switch – can be read by the controller.
