CONFIGURATION GUIDELINES
These guidelines apply to control panels that support V-Plex polling loop devices. Some of these control panels
may have additional limitations; refer to the control panel's Installation & Setup Guide for specific power and
wiring requirements.
Maximum number of devices:
•
All input loops (combined) = 64 devices max.
•
All input loops (combined) plus
1
output loop =
11
9 devices max.
Maximum wire length limits:
Refer to Table
1
(at right) for wire length per gauge,
and observe the maximum wire length limits.
•
No individual wire run can exceed 2400 ft. max.
•
1
input loop plus
1
output loop (combined) = 4000 ft. max
•
All input loops (combined) plus
1
output loop = 6400 ft. max
Note:
Reduce wire length by ½ if using unshielded
wire in conduit, or if using shielded wire.
Maximum Current:
•
All input loops (combined) =
1
28mA maximum current limit.
•
Each output loop =
1
28mA
•
Any single wire run = 64mA
