Define Instruments P2P-R Specifications

Wireless Repeater Node

The P2P-R Wireless Repeater is the perfect addition to a Twin
Link system where the Input and Output nodes are out of
range, or a line of sight connection cannot be established.

›

Extend the transmission range of your Twin Link

Add up to 1.5km (0.9mi) Line Of Sight for each Repeater

›

Get around RF obstacles

›

Easy integration with your Twin Link

›

Up to 15 Repeaters per Point-to-Point system

That’s a total wireless transmission distance of up to 24km (14.9mi) LOS

Example of Use

P2P-R

A wireless Link is needed between a reservoir and
a pump station. The Input Node will measure the
incoming 4–20mA signal from the reservoir level
sensor, and the Output Node will output 4–20mA
to the pump controller, to control the water levels
in the reservoir.

The reservoir is over a hill, so there is no line of
sight between it and the pump station. By placing
a Repeater at the top of the hill within line of sight
of both the Input and Output nodes, a successful
Link can easily be made.
