3 Controller
Parallel I/O unit 3-69
Table 3-22 ： Electrical specifications of input circuits
Table 3-23 ： Electrical specifications for the output circuits
The output circuit protective fuses prevent failure in case of load short-circuit and
improper connections. Please do not connect loads that cause the current to exceed
the maximum rated current. If the maximum rated current is exceeded, the internal
transistors may be damaged.
