Distributors and separators for the RS-485 bus


We invite you to familiarize yourself with our offer of devices that amplify the RS-485 bus signal. Thanks to the use of a separator, it is possible to increase the original number of end devices in an installation based on 2-wire RS-485 bus systems. RS-485 bus separators are also devices that eliminate transmission interference in industrial installations resulting from potential differences. Currently, the most popular products are:

EW-485/1/2/So - characterized by full transmission of data packets in both directions (half duplex), with a transmission speed of up to 500 kbaud. Once transmitting is complete, it frees up the transmission line very quickly, which is important for efficient setups. It is used in alarm systems, CCTV, access control, industrial automation (can be used in Modbus RTU networks).

EW-485/4/2/So - is a bidirectional amplifier and splitter of telemetry signals using the RS-485 bus with a transmission speed of up to 500 kbaud. It allows you to expand the network to a maximum of 512 devices using low-impedance drivers in the connected devices. The distributor is perfect for CCTV systems, access control and industrial automation to achieve a star topology, where damage (short circuit) of one of the branches does not block transmission on other branches. Each output has a switchable 120 Ohm terminating resistor.
