App
A-1-2 Basic I/O Units
z CJ1W-IA111 AC Input Unit (100 VAC, 16 points)
*1 The Input ON and OFF response times for Basic I/O Units can be set to 0 ms, 0.5 ms, 1 ms, 2 ms, 4 ms, 8 ms,
16 ms, or 32 ms in the PLC Setup. When the response times have been set to 0 ms, the ON response time will
be 10 ms maximum and the OFF response time will be 40 ms maximum due to internal element delays.
*2 Use an input voltage of 90 VAC or higher when connecting 2-wire sensors.
*3 Terminal numbers A0 to A8 and B0 to B8 are used in this manual, but they are not printed on the Unit.
