CJ1W-IA111 AC Input Unit (100 VAC, 16 points)
*1 Can be set to 0 ms, 0.5 ms, 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, or 32ms in the Unit Information settings. 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 the external connection and terminal-device variable diagrams.
They are not printed on the Units.
