I = leakage current in mA
R = bleeder resistance
The following are examples of how to connect I/O devices to I/O Units. During
wiring, work slowly and carefully. If an input device is connected to an Output
Unit, damage may result. Check all I/O devices to make sure they meet the spec-
ifications (refer to Appendix B Specifications).
