• Wiring the Pulse Input Module and Digital Input Modules (-D05, -D24)
Note
• With the pulse input module and 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 pulse input module and digital input module, the
terminal arrangement differs from that of clamp terminals, therefore wire according to the markings on the terminal
cover. Do not connect anything to the b terminals.
Wiring the Pulse Input and Digital Input (-D05) Modules
• Transistor input • Contact input • 5-V logic input
Main Input Specifications (for Pulse Input and Digital Input (-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
Minimum detection pulse width:
Pulse input: 4 µs
Digital input (-D05): Twice the measurement interval or more
Input threshold level: • Pulse input
Non-voltage contact or open collector:
Counts when changing from contact open (100 kΩ or more) to
contact close (100 Ω or less)
5-V logic: Counts when changing from 1 V or less to 3 V or more
• Digital input (-D05)
Non-voltage contact or open collector:
ON at 100 Ω or less and OFF at 100 kΩ or more
5-V logic: OFF at 1 V or less and ON at 3 V or more
Contact/transistor rating:
