Specifications of Basic I/O Units Appendix A
When overcurrent is detected, the ERR indicator will light, and the corresponding flag in the Basic I/O Unit
Information Area (A050 to A069) will turn ON.
Terminal Connections
When wiring, pay careful attention to the polarity of the external power supply. The load may operate if the
polarity is reversed.
Note Terminal numbers A0 to A9 and B0 to B9 are used in this manual, but they are not printed on the Unit.
