waveshare Industrial Isolated 8-ch RS485 Hub, Extend 8-ch RS485 Slave Ports via 1-ch RS485 Master Port,with Isolation and Relay,Support Rail-Mount, 300~460800bps (Self-Adaptive) Baud Rate, DC 9~24V

Overview RS485-HUB-8P is an industrial grade isolated RS485 hub that can expand 8-ch RS485 slave ports through 1-ch RS485 master port, can realize relay, extension and isolation functions of RS485 network, with screw terminal for power input. Rail-mount case design, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring... Features 1. Industrial isolation protection: Built-in photoelectric isolation protection circuit, can effectively isolate RS485 master and slave devices to avoid the damage of ground potential difference between devices, anti-electrostatic, lightningproof & anti-surge, which is suitable for the industrial environment with high reliability and safety requirements. 2. Wide baud rate range: Supports 300～460800bps wide baud rate communication range (self-adaptive) 3. Rail-Mount Support: Supports 35mm standard guide rail, with rail-mount buckle, easy to install. Specifications Interface standard : Compliant with RS485 standard Physical interface: RS485 screw terminals Baud rate: 300~460800bps (self-adaptive) supported nodes: Each RS485 port supports up to 32 nodes Communication distance : 1200m (9600bps), the higher rate the shorter distance Operating mode : RS485 two-wire (A, B), half-duplex transparent transmission Power supply : DC 9~24V Operating temperature: -45 ~ +85℃ Environment humidity :<95%RH Transmission medium: Normal parallel cables/twisted-pair cables Online Development Resources /User Manual:// bit.ly/3qyi3U3 Package Content RS485-HUB-8P x1
