Wiring the Terminal Block

The module terminal block has eight shield terminals provided as frame ground connections for input wire

shielding. It also provides eight external encoder disable pins used to externally gate each input. A low input

allows each channel (or channel pair) to operate. There are also 8 counter enable lines that are compatible with 5,

12, and 24 VDC inputs. If pulled high with one of these inputs, a channel (or channel pair) is disabled.
