RS485-HUB-4P is an industrial RS485 hub with galvanic isolation and four subordinate ports, enabling safe and stable operation in serial bus networks in a star topology. Ideal for applications in automation, IoT and industrial systems.
RS485-HUB-4P is an industrial-grade RS485 bus hub that enables splitting one main port into four independent subordinate ports with full galvanic isolation. The relay-based design ensures stable signal transmission in a star topology, eliminating interference typical of many devices connected in parallel. This solution is ideal for data acquisition systems, automation, monitoring and IoT gateways.
The device supports half-duplex transmission in the range of 300–460800 bps with autodetection of speed. It supports up to 32 devices on each port and communication over distances up to 1200 m (at 9600 bps). The housing is designed for mounting on a 35 mm DIN rail. Power is supplied via a screw terminal in the voltage range from 7 V to 36 V DC.
