Application Examples
Need to use the WP2P to switch high current, high voltage?
This is achieved by using interface relays, outlined in this FAQ.
Digital & Analogue Wireless Point to Point System
LOW COST WIRELESS DIGITAL AND ANALOGUE SIGNAL TRANSMISSION
The Digital and Analogue WP2P system is a wireless solution used to measure levels, pressure or flow sensors, without needing to trench a cable.
The system comprises two digital and analogue wireless point to point modules that are located within line of sight of each other. Each unit has one 0-20mA or 0-10v input, one 0-20mA or 0-10v output, two switched
inputs and two relay outputs, which allows you to transmit an analogue sensor reading and two digital signals.
inputs and two relay outputs, which allows you to transmit an analogue sensor reading and two digital signals.
For example you can measure a water storage level or provide a control signal for a VSD, while also turning pumps on or off and receiving alerts for faults.
No configuration or programming is required, simply connect the power, and go!
KEY FEATURES
• USB interface for on-site firmware upgrades
• Isolated I/O interface section for improved power saving operation
• “Failsafe” output hold feature during communications failure
• Line of sight operational range up to 350m with supplied antennas, 2km with our optional whip antennas, or 4km with our optional Yagi antennas
• 900MHz Digital Modulation radios for added security
• “Link status” LED provides confirmation that the modules are communicating
Note: For these radio systems to work they must have clear “line of sight” between the modules. Depending on the terrain and the antennas being used, the WP2P system can transmit up to four kilometres. Where there are obstacles, hilly terrain or to increase the range, QTech’s WP2P Repeater module can be used to provide a reliable communications path.
We also provide a range of suitable Solar power supplies, DC power supplies and DIN rail mounting option.
