I NPUT A AND B C ONNECTORS
Each ClearPath I/O connector on the SC Hub has two inputs associated
with it: Input A and Input B. Each input has its own 4-pin Molex
connector as shown below.
The inputs are designed for use with 24VDC,

NPN type sensors or
mechanical switches. They are optically isolated, digitally filtered, current
limited, and reverse polarity protected for robust, long-term performance.
For more on how the inputs work, see the input circuit schematic (below)
and Appendix G, Wiring Inputs A and B.

Maximum Input Cable Length
Cables used for SC inputs can be a maximum of 100 feet (30 m) long.
However, longer cable runs may be possible if the cable stock is of high
quality, low capacitance, twisted pair construction. Contact Teknic if you
need input cables longer than 100 feet (30 m).

ClearPath -SC motors can accept inputs from devices with logic high ranging from 5-24VDC,
but the SC Hub, by default, accepts 24VDC NPN type sensors or simple mechanical
switches.
