• 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:

Contact with a rating of 15 VDC or greater and 30 mA or greater

Vce and Ic are transistors with ratings of 15 VDC or more, and 30

mA or more, respectively.

Terminal type: Clamp

Applicable wire size: 0.14 to 1.5 mm

(AWG26 to 16)

Wiring the Digital Input (-D24) Module

24 V

• 24-V logic input

Main Input Specifications (for Digital Input (-D24))

Input type: DI (24-V logic)

Input format: Common potential between channels

Minimum 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

(AWG26 to 16)
