Description
The URLS 25/50 Series of terminal blocks provide an IDC connection solution for
distribution terminal and cross-connect applications. All blocks in this series have sealant-filled connections for maximum corrosion protection when used in outdoor or
environmentally-challenging installations. All electrical connections are IDC (insulation
displacement connection), made without removing the insulation from the wire.
The contact terminals slice through the insulation and create a gas-tight contact at the
copper/terminal interface.
The URLS25S block consists of 25 URLS input connector pairs factory-wired to 25 URLS
output connector pairs. The URLS50S blocks consist of two 25-pair sheathed cable input
stubs, with or without 710 connectors, factory-wired to 50 URLS connector pairs. The
URLSP25S blocks consist of a 25-pair, 26-gauge sheathed input stub, available with or
without 710 connectors, factory-wired to a 25-pair protector panel.
The output from the protector panel is factory-wired to 25 URLS connector pairs. The
input stubs provide a fuse link for compliance with UL safety specifications per UL497. The
protector panel accepts industry standard 5-pin protector modules, which can be ordered
separately or included with the unit by adding the protector module catalog number to
the unit’s catalog number.
ActCaps guide single-pair cable into proper terminating position and connect the cable
pair to the metallic contacts. Wires are terminated by pressing down on the ActCap,
requiring only a push of the installer’s thumb. The ActCaps can terminate 20- through 26gauge (.4 to .8 mm) conductors. Test results verify that ActCaps
can terminate 24-gauge wire more than 250 times with stable,
low contact resistance.
URLS blocks are molded from glass-filled Valox for long-term
outdoor performance. Electrical terminals are fabricated from
tin-plated phosphor bronze for low contact resistance. URLS
blocks are secured in a metal mounting fame, which is
additionally protected with our off-white finishing process.
For ease of installation, Emerson Network Power URLS25/50
Series blocks may be panel-mounted or bracket-mounted on an
industry-standard 89 stand-off bracket (Emerson R891S Series).
Application
The URLS25/50 Series is designed for copper wire terminals and
cross connect systems throughout the communications network. This series is ideal for use in outdoor remote electronic
equipment enclosures with limited space for wire termination.
