Distributor, splitter RS-485 bus with optical separation, 2-way communications with half-duplex mode, EW-485/4/2/So
EW-485/4/2/So is designed for splitting and separation of telemetry signals used in industrial, building automation and other systems using the RS-485 bus. Packets sent to the MASTER port are regenerated and in the same form sent to four separated SLAVE ports, which provides a 4-fold increase in the length of the entire bus. Packets received from any SLAVE port are directed only to the MASTER port. The data is not transferred between the SLAVE ports. The RS-485 separator / splitter is perfect for CCTV systems, access control and industrial automation to obtain a star topology, where the damage (short-circuit) of one section does not block transmission on other sections. Each RS-485 port have built-in a termination resistor 120 Ohm switched on by the wire link.
The EW-485/4/2/So use low-impedance RS-485 drivers, which allows the network to be expanded up to 512 devices if low-impedance drivers are used in all connected devices.
Galvanic separation protects each section and connected devices against the ground loop potentials and transmission disturbances.
600W @ 8/20uS surge protection and short-circuit protection, provide high resistance to damage connected devices against the over voltages, lightning discharges, and vandalism.
