Application
Use on twisted pair lines, eg those found in process control
equipment, modems and computer communications interfaces.
Features and benefits
Protectors | Twisted pair data, signal and telephone lines
Suitable for most twisted pair signalling applications.
Available for working voltages of up to 6, 15, 30 and 50
volts and telephone pairs with a maximum working or
ringing voltage of 190 volts.
Low let-through voltage between all lines.
Provides repeated protection in lightning intense environments.
Low in-line resistance minimises unnecessary reductions in signal
strength.
Strong, flame retardant, ABS housing.
Supplied ready for flat mounting on base or side.
Built-in DIN rail foot for simple clip-on mounting to top hat
DIN rails.
Colour coded terminals give a quick and easy installation check –
grey for the dirty (line) end and green for the clean end.
Screen terminal enables easy connection of cable screen to earth.
Substantial earth stud to enable effective earthing.
Integral earthing plate enables enhanced connection to earth via
a CME kit.
UK Oftel Approval NS/G/1235/W/100025.
Three rows of protectors, inside a
control cabinet, each installed on a
CME 16 combined mounting and
earthing kit.
Installation
Connect in series with the data communication or signal line either
near where it enters or leaves the building or close to the equipment
being protected (eg within its control panel). Either way, it must be
very close to the systems earth star point. Install protectors either
within an existing cabinet/cubicle or in a separate enclosure.
Install in series (in line).
Suitable accessories
Simultaneously mount and earth up to 4 of these protectors on a
CME 4, up to 8 on a CME 8, up to 16 on a CME 16 or up to 32
on a CME 32. Enclosures suitable for up to two (WBX 2/G) or
three (WBX 3/G) protectors, or a CME 4 and its associated
protectors (WBX 4), CME 8 and protectors (WBX 8) or one or two
CME 16 kits and protectors (WBX 16/2/G) are available.
From line
Twisted pair data, signal and telephone lines
In damp or dirty environments, ready boxed versions (ESP **D/BX or
/2BX) are available. If the protector is to be mounted directly onto a PCB,
use the ESP PCB/**D protectors. For systems requiring a very low
resistance, higher current or higher bandwidth, the ESP **E series may be
more suitable. For three-wire RTD applications, use the ESP RTD, and
for applications where there are many lines to be protected, the ESP **Q
series may be suitable. Other protectors for telephone lines are available.
DIRTY
Earth
Protectors can be flat mounted via
their base (left) or side, or mounted on
top hat DIN rail (right) via an
integral spring loaded DIN rail foot.
