Wiring Your Controller for High-Speed Counter
Applications
To wire the controller for high-speed counter applications use input terminals I/0,
I/1, I/2, and I/3. Refer to chapter 12 for information on using the high-speed
counter.
Shielded cable is required for high-speed input signals 0–3 when the filter setting is
set to either 0.10 ms or 0.075 ms. We recommend Belden #9503 or equivalent for
lengths up to 305 m (1000 ft). Shields should be grounded only at the signal source
end of the cable. Ground the shield to the case of the signal source, so energy
coupled to the shield will not be delivered to signal source’s electronics.
