CJ1W-ID201 DC Input Unit (12 to 24-VDC, 8 Points)
*1 The ON response time will be 20 s maximum and OFF response time will be 400 s maximum even if the response time are set to 0 ms
due to internal element delays.
*2 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.
