Link Extender
C O MPO NE NTS
12.2
Model
LUT-LINK-EXT: extends the total wire length allowed for use on the inter-processor and Module Interface links from 305m (1,000 feet) to 610m (2,000 feet).
Input voltage
100/120, 220/240VAC, 50/60Hz
Regulatory approvals
UL, CSA, NOM, CE, C-Tick
Environment
Ambient temperature: 0-40째C, 32-104째F Ambient humidity: 0-90% humidity, non-condensing. Indoor use only.
Line-voltage
Use copper wire only, supply conductors 60/75째C.
Low-voltage wire type
One pair twisted shielded 1.0-0.5mm (#18-22 AWG) Class 2/PELV wiring.
Low-voltage wiring configuration
See figures 3, 4, page 12.3.
Low-voltage connections
One 4-pin removable terminal block. Each terminal will accept up to four 1.0mm (#18 AWG) wires.
Addressing
Not required.
Diagnostics
LEDs provide diagnostics for troubleshooting communication on the links.
ESD protection
Meets or exceeds IEC 61000-4-2.
Surge protection
Meets or exceeds ANSI/IEEE standard c62.41.
Dimensions
197mm (7-3/4 inches) x 127mm (5 inches) x 64mm (2-1/2 inches)
Mounting
Mounts on a standard 105mm (4 inches) x 105mm (4 inches) junction box. Lutron backbox 241496 may be used.
Shipping weight
1.1kg (2.4 pounds)
Using special cable
Special wire can be used to extend the total wire length on the inter-processor and Module Interface links from 305m (1,000 feet) to 1220m (4,000 feet) without the use of a Link Extender, and to 2240m (8,000 feet) with the use of a Link Extender. Refer to HomeWorks application note #62 for details and wire specifications.
