Power Requirements:

•24 Vdc, 500 mA

•14 AWG, 2 conductor, stranded cable (Belden 5100UE or equivalent)

•Up to 10 sensors per power supply

•Up to 1,000 feet max power cable length per power supply

•Larger power cable and/or additional power supplies may be required for longer cable runs and/or increased number of sensors

Contact Honeywell Analytics for help with all power requirements.

Communication Requirements:

•24 AWG twisted pair, shielded (Belden 9841 or equivalent)

•Network can be up to 2,000 feet per channel

•Avoid “T-taps” if possible

•Do not exceed 65 feet per T-tap

•Do not exceen 130 feet total of all T-taps

•Communication wire shield must be connected to shield terminal(s) of controller (J23-J24)

•Channels 1-2-3: Modbus protocol — Communicates only with Modbus devices

•Channel 4: Modbus output only — No sensor can be connected to Channel 4
