Wiring the Pulse Input Module and Digital Input Module
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.
Wiring the Pulse Input and Digital Input (-D05)
• Transistor input • Contact input • 5-V logic input
5 V
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 approx. 5 V/approx. 5 kΩ, common potential between
channels
Minimum detection pulse width:
Pulse input: 40 μs
Digital input (-D05): Twice the measurement interval or more
Input threshold level:
• Pulse input
Non-voltage contact or open collector:
Count upon change from contact open (100 kΩ or
more) to contact close (100 Ω or less)
5-V logic: Count upon change from 1 V or less to 3 V or more
• Digital input (-D05)
Non-voltage contact or open collector:
100 Ω or less: ON, 100 kΩ or more: OFF
5-V logic: OFF at 1 V or less and ON at 3 V or more
Contact/Transistor rating:
Contact with a rating of 15 VDC or greater and 30 mA or greater
Transistor with a rating of Vce > 15 VDC and Ic > 30 mA
Terminal type: Clamp
Applicable wire size: 0.14 to 1.5 mm 2 (AWG26 to 16)
Wiring Digital Input (-D24)
24V
• 24 V logic input
Main Input Specifications (for Digital Input (-D24))
Input type: DI (24-V logic)
Input format: Common potential between channels
Min. detection pulse width: Twice the sampling interval or more
Input threshold level: 24-V logic: OFF at 6 V or less and ON at 16 V or greater
Terminal type:
Clamp
Applicable wire size: 0.14 to 1.5 mm 2 (AWG26 to 16)
