Extension Loop Limits:
- Same as for the input polling loop. Input Loop Limits:
- 128mA max. No more than 64mA
on any individual wire run.
- No individual wire run may exceed:

- Total length of all wire runs combined cannot
exceed 4000 ft. (2000 ft. if using unshielded
wire in conduit or shielded wire).
Combined Input and Extension Polling Loop Limits:
- No more than 119 devices combined.
- Total length of all wire runs on all loops combined can-
not exceed 6400 ft. (3200 ft. if using unshielded wire in
conduit or shielded wire)

Up to 8 modules may be connected
in parallel. Extension loops will be
electrically isolated if blue jumper
on each 4297 is left in tact.
Combined Input and Extension Loop Limits:
- No more than 119 devices combined on all loops
- To calculate the maximum wire run allowed on each extension loop:
1. Determine the total wire length of all input loops combined.
2. Subtract this number from 6400 ft. (3200 ft. for shielded cable or
unshielded cable in conduit).
The result is the maximum wire run length for each extension loop.
