(Specified wiring: Belden 8641(24 AWG, 300V, Part numbers 135-8641); Belden 8761 (22 AWG, 300 V, not stocked by
Copeland; or a 600V-shielded 22 AWG equivalent, part number 135-0600) supporting a maximum cable distance of 4,000 ft
(1,219 m) between the Supervisory controller and end-device. Belden 9855 may be used as an alternative in noisy
environments, and is not recommended in other situations.

Supervisory Controller supports four independent MODBUS networks – so the user can have multiple
MODBUS addresses on the different networks. However, the total number of devices in both networks combined, cannot ex-
ceed 99.
