RS485 Protector DIN

0,00 

The AXON RS485 Protector DIN is designed for surge protection of electronic appliances operating in industrial control systems based on RS485 transmission or variants thereof with the voltage not higher than 5V. The device incorporates protective elements that limit overvoltages between the transmission lines and the PE protective wire and simultaneously discharges the surge energy to the earth. The device also uses protective elements to limit the dangerous voltage that may occur between lines A and B. With this extensive protection the AXON RS485 Protector DIN protects the connected equipment in a comprehensive way. The device‘s housing is designed for mounting in control and distribution cabinets equipped with the popular 35mm DIN rail. Terminals A and B are used to connect transmission lines to be protected, while the third terminal can be used by the installer as a signal earth if required. The earthing wire terminated with a fork terminal is led out of the housing and connected directly to it. The devices are asymmetric surge protectors. The transmission line should be connected to the “Line” terminals, while the “Equip.” terminal is used to connect the protected appliance.
