FEATURES
•Physical isolation between two channels.
•Supports installation of larger networks.
•Uses LONWORKS network protocol.
•Two-piece design allows pre-wiring and cable testing prior to installation.
•Color-coded screw terminals and polarity-insensitive power and network connections minimize chance of incorrect wiring.
•Operates from 16-30 Vac or Vdc, allowing router to be powered from same source as sensors and actuators.
•Power and network wiring are looped through each base plate, providing undisrupted network continuity if replacing router.
•Two front panel jacks that access the twisted pair network without requiring disassembly.
•Front panel bar code including model, revision, and two removable Echelon® Neuron® chip ID stickers.
SPECIFICATIONS
The Q7751A Router is a two-piece design allowing prewiring and cable testing prior to installing the electronic component. The front panel includes a printed circuit board (PCB) with active electronics. The front panel also has a service switch, a power/wink LED, an activity LED, and two network connectors. Network and power are connected to screw terminals located on a type 2 base plate where the router is plugged. Wiring is never directly connected to a router.
