Wiring the Digital Input Modules (-D05, -D24)
Note
• With the digital input module, the (–) terminal and unassigned terminals on all channels are
shorted internally.
• When the screw terminal plate (model 772080) is connected to the digital input module, the
terminal arrangement differs from that of clamp terminals, therefore wire according to the
markings on the terminal cover.
Wiring with the -D05 Option
• Transistor input • Contact input • 5V logic input
Main Input Specifications (-D05)
Input type: DI (non-voltage contact, open collector, and 5 V logic)
Input format: Pull-up at approximately 5 V/approximately 5 kΩ, common
electric potential between channels
Min. detection pulse width:
Twice the sampling interval or more
Input threshold level:
Non-voltage contact, open collector: ON at 100 Ω or less and
OFF at 100 kΩ or greater
5-V logic: OFF at 1 V or less and ON at 3 V or greater
Contact/transistor rating:
