EW-485/4/1/SO is a professional, active RS-485 bus distributor designed for complex CCTV systems, access control systems, and building automation. This device plays a key role in situations where it is necessary to split a control signal from a single source, such as a digital video recorder (DVR), a control keyboard with a joystick, or a PC, into four independent branches. Thanks to the use of advanced signal amplification technology, the distributor allows for a significant extension of the maximum bus length, which is invaluable in large industrial facilities.
The main advantage of the device is full optical separation of 1 kV DC. This isolation occurs not only between the input and outputs but also independently between each of the four output ports. Such a solution guarantees the highest level of safety, protecting terminal devices against the effects of atmospheric discharges, surges, and potential differences that often occur in extensive installations. As a result, a failure in one part of the system does not propagate to the others, which drastically increases the reliability of the entire infrastructure.
The use of the EW-485/4/1/SO enables changing the network topology from a classic bus (serial) to a star topology. This is a much more flexible and fault-tolerant solution – damage or a short circuit in one of the branches does not affect the operation of the remaining branches of the system. The device supports transmission speeds of up to 1 Mbit, which ensures smooth and trouble-free communication even in the most demanding applications. The robust construction and wide supply voltage range (9-24V DC) make it a reliable product that is easy to adapt to existing power infrastructure. The distributor is an ideal solution for installers looking for reliable methods to secure and organize communication buses in modern surveillance and control systems.
