Dimensions and installation
Selection questions
Are the mechanical dimensions shared by 3N and 3P?
Yes. The output mode changes, while the supplied GDC-3 manufacturer page uses the same 69 × 56 × 38 mm envelope.
What must be confirmed before wiring?
Confirm DC 12–24 V supply, NPN or PNP input compatibility, cable assignment and the physical slot position.
