Storage: -40°C to 70°C (-40°F to 158°F)

Terminations

Inputs/Outputs: 6.3 mm (1/4 in.) Spade Lugs

FC Bus, SA Bus, and Supply Power: 4-Wire and 2-Wire Pluggable Screw Terminal Blocks

FC and SA Bus Modular Ports: RJ-12 6-Pin Modular Jacks

Controller Addressing for BACnet MSTP

DIP switch set; valid field controller device addresses 4–127

(Device addresses 0–3 and 128–255 are reserved and not valid field controller addresses.)

Controller Addressing for N2

DIP switch set; valid field controller device addresses 1–254

Communications Bus

RS-485: selectable between BACnet MSTP or N2

FC Bus: 0.6 mm (22 AWG) standard 3-wire, twisted, shielded cable recommended between the supervisory controller and controller

10/100 Mbps; 8-pin RJ-45 connector

SA Bus: 0.6 mm (22 AWG) stranded, 4-wire (2-twisted pairs) shielded cable recommended from the VMA controller for network sensors and other sensor/actuator devices; includes a terminal to source 15 VDC supply power from VMA to SA Bus devices
Note: For more information, refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034), Metasys IP Networks for BACnet/IP Controllers Configuration Guide (LIT-12012458)
