The connected load is switched via the digital output (relay contacts) from the control system. The internal system voltage is used to trigger the relays. Note that the power jumper contacts supply both "N" (common point) and switched output voltages (this may DC or AC). The switched status of the relay outputs is shown by a LED. The module 2-channel, 4-conductor device and actuators with a ground (earth) wire may be directly connected to the module. Attention: An additional supply module must be added for the supply 30 V!
