A-2-2 Basic I/O Units
CJ1W-ID212 DC Input Unit (24 VDC, 16 Points)
*1 The ON response time will be 15 s maximum and OFF response time will be 90 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.
