8-channel DC 24 V digital output terminal
The 8-channel DC 24 V digital output terminal transmits binary control signals from the automation device to the
connected actuators (e.g. magnet valves, contactors, transmitters, relays or other electrical appliances).
The bus terminal has 8 output channels and allows for direct connection of actuators with 2-conductor technology.
These are not outputs in the form of potential-free contacts, but rather actively switched 24 V signals.
