CJ-series Interrupt Input Units

CJ1W-INT01

CJ1W-INT01

High-speed Starting of I/O Interrupt
Tasks. Use Up to Two Units for a
Total of Up to 32 Interrupt Inputs.

• Receive inputs to start I/O interrupt tasks. When the
Interrupt Input Unit receives an input, the CPU Unit will
interrupt execution of the cyclic tasks in the normal
program and execute an I/O interrupt task.

CSM_CJ1W-INT01_DS_E_2_2

Features

• High-speed ON response of 0.05 ms

• Use up to 32 interrupt inputs with up to two Units per CPU Unit.

• Applicable with both NPN and PNP output devices. Polarity selection is not required. *

* The same polarity is used for the same common.

Note: 1. Can be used only on CPU Racks, and not on Expansion Racks.

2. The locations where the Units can be mounted depend on the CPU Rack and the CPU Unit model.

CJ2H-CPU6@-EIP: From the slot next to the CPU Unit until the fourth slot.
CJ1G, CJ1H: From the slot next to the CPU Unit until the fifth slot.
CJ1M: From the slot next to the CPU Unit until the third slot. (Final order entry date for CJ1M :The end of March, 2021)

3. With the SYSMAC NJ-series Controllers,Interrupt Input Units can be used as normal Basic Input Units. They cannot be used to start I/O
interrupt tasks.

CJ1W-INT01 2 Units *1*4

*1. The Interrupt Input Unit can be mounted in slots 0 to 4 on the CJ1-CPU Rack. An Incorrect Unit/Expansion Rack Connection error will occur if

an Interrupt Input Unit is mounted to slot 5 or higher.

*2. Connectable slot position changes with the CPU Unit.

•CJ1M-CPU@@: Slot No.0 to 2

• CJ2H-CPU@@-EIP: Slot No.0 to 3

• CPU Unit other than abobe: Slot No.0 to 4

If the Unit is mounted to the slot other than abobe, I/O setting error will occur. (Final order entry date for CJ1M :The end of March, 2021)
*3. An I/O setting error will occur if an Interrupt Input Unit is mounted to an Expansion Rack.
*4. Interrupt Input Units can be used as normal Basic Input Units. They cannot be used to start I/O interrupt tasks.
