Terminal Connections
Note 1. Use an input voltage of 90 V AC or less when connecting 2-wire sensors.
2. Terminal numbers A0 to A9 and B0 to B9 are used in this manual, but they are not printed on the Unit.
CJ1W-INT01 Interrupt Input Unit (16 Points)
Circuit Configuration
• Up to two Interrupt Input Units can be mounted to the CPU Rack, but they must be connected as one the
five Unit immediately next to the CPU Unit. If an Interrupt Input Unit is connected in any other position, an
I/O setting error will occur.
• Interrupts cannot be used when an Interrupt Input Unit is mounted to an Expansion Rack.
