*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 Terminal numbers A0 to A8 and B0 to B8 are used in this manual, but they are not printed on the Unit.
Note Although 16 I/O bits (1 word) are allocated, only 8 of these can be used for external I/O. This Unit is also
treated as a 16-point I/O Unit in the I/O tables.
