Examples of External Wiring (Rotary Encoder)
10.8.1 1-phase 1-input [C235 to C245]
The following examples of wiring apply to the cases where C235 is used.
When another high-speed counter number is used, wire the counter referring to the following diagrams.
It is recommended to use shielded twisted-pair cables for connection cables. Ground the shield of each
shielded cable only on the PLC side.
1) NPN open collector transistor output rotary encoder
