The maximum SLC wiring distance is 10,000 feet (3,000 meters) with a maximum loop resistance of 40 ohms (Page 13, 173) [1].

This distance limit applies to the total length of all branches combined in the circuit (Page 173) [1].

While the general loop limit is 40 ohms, specific resistance limits apply to certain devices: 40 ohms for standard monitor modules and 20 ohms for mini-modules (Page 173) [1].
