A C200H-COV11 Cover is provided as an I/O Unit cover for Units that use 10P
terminal block connectors. After the I/O wiring has been completed, slide the
cover up from the bottom, as shown in the illustration below.
If a two-wire sensor is used with a 12-VDC or 24-VDC input device, make sure
that the following conditions are satisfied. Malfunctions will occur if these condi-
tions are not satisfied.
• The relationship between the PC ON voltage and the sensor residual voltage is
• The relationship between the PC ON current and the sensor control output
• The relationship between the PC OFF current and sensor leakage current is as

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 ).
