Wireless Connect single-channel, two-way wireless discrete signal extender

There are times when you need to connect a discrete sensor to the controller, or simply use the button to control a remote pump or lighting. For example, connect the PR-200 output to a remote relay, and pulling wires is either not profitable (if there is only one sensor), or a long distance. This device was created for these purposes.
MDS-R1 modules, together with ATR1-433 antenna modules, are designed for two-way wireless transmission of the status of contacts of sensors, relays, buttons and other devices with a “dry contact” or “open collector” type output. The input and output discrete channels are galvanically isolated.

The device works stably even in a heavily loaded air. This is achieved by using highly efficient LoRa radio technology in conjunction with digital signal processing. Additional reliability is ensured by the fact that a floating algorithm is used, with a random time range, and this eliminates interference from the same type of equipment. The device constantly monitors the presence of communication between the modules, if any accident occurs on the transmitting side, or the transmitter breaks down, then the "stop" command will automatically work on the receiving side after 1 minute. This function can be used at facilities where it is necessary to control an emergency power outage or theft of lead wires at the facility. If you install the module on the final electric pole, then if the wire is damaged at any point, you can monitor the state of the power line.
