The figure below shows some of control systems employing the C20. The
maximum number of I/O points per system is 28 if the DC input type

With the DC input type CPU, the number of I/Os can be increased to 56,
84, 112, or 140 points. This is accomplished by using up to two expansion
\/O units. With the AC type. the number of |/O points can be 52, 78, 104, or
