Description
Radio bridge, long range radio, low power consumption
Mod. LINK-R4
The MARCONI half-duplex radio link is used for the remote control of gates, lights, alarms, irrigation systems, etc. It is able to guarantee very long distance communications, high sensitivity, reduced energy consumption and high immunity to interference. It works thanks to the combination of LINK-T4E and LINK-R4. The LINK-T4E is a transmitter with encrypted communication capable of driving the LINK R4 receiver. This system, in addition to allowing remote loads to be activated, is ideal for very long distance activation and control applications, such as irrigation and alarm systems. Cyclic reception also allows for consumption of less than 1 mA, allowing use in battery-powered applications.
BIDIRECTIONAL
Bidirectional communication allows you to know the status of the activated output. The LINK-T4E transmitter allows up to 5km of bidirectional transmission, LINK-T4X up to 1km.
The use of LoRa technology enables long-range transmissions thanks to its point-to-point wireless communication system
