Digital 24 V Input (Changeover Input)

Digital 24 V Input
DOK-SUPPL*-VDP16/40/60-PR02-EN-P
X21 – The selection, which of the VDP displays connected to the Y-Repeater is
activated, occurs via a digital 24 V input.
As the image signals are transmitted to both VDP displays, data can only
be entered with the active VDP.
