Signal type: VI = voltage input;VO = voltage output
Note
The two "+" or "M" terminals are jumpered in the connector. This ensures the 24 V voltage is
looped through. The maximum current can be limited through the current carrying capacity of
the cable. The current carrying capacity of the cable depends, for example, on the type of cable
installation (cable duct, laying on a cable rack, etc.).
Wiring the screw terminal block
The 24 V DC load power supply required is wired to screw terminal block X124.
