The AMSAMOTION RS485 Repeater is a device that is used to extend the distance of RS485 communication equipment in industrial environments. RS485 is a widely-used communication standard for serial data transmission, and it is commonly used in industrial automation applications.

The RS485 Repeater is designed to support 1-way RS485 to 1-way RS485 communication, which means that it can transmit data between two devices over a single pair of wires. It is an asynchronous, half-duplex device, which means that it can transmit data in both directions, but only one direction at a time.

The RS485 Repeater has several features that make it suitable for use in industrial environments. It has a built-in DC-DC power isolation module that provides isolation voltage of 1500V, which helps to protect against electrical noise and other interference. It also has optocouplers that isolate the RS485 master-slave network, ensuring that data communication is not affected by ground loop and common mode voltage differences.
