Specifications of Basic I/O Units Appendix A
• The input power polarity can be connected in either direction.
• Be sure to wire both terminals 23 and 24 (COM0), and set the same polarity for both pins.
• Be sure to wire both terminals 3 and 4 (COM1), and set the same polarity for both pins.
Note The ON response time will be 20 µs maximum and OFF response time will be 300 µs maximum even if
the response times are set to 0 ms due to internal element delays.
