- The first half 8 points is acceptable for input/output
and the second half 8 points is unacceptable area for
this module.

[3] Maximum number of input/output points and allocation of input/output relays
Each control module has own maximum number of control input/output points. However, number of relay
points that affect maximum number of control input/output points varies with each model. Be careful that
these are different from number of relay allocation points.
