Isolated 4 Channels RS485 Hub/Splitter/Repeater, 2500V Optical Isolation, Rail-mount Support
$38.88
💡 1-to-4 Star Topology & 2500V Optical Isolation
The 4CH-HUB-RS485 is an active signal repeater/splitter that can convert a standard daisy-chain network into a very reliable 1-to-4 star topology. Featuring 2500V optical isolation on the downlink ports, it guarantees that a short circuit or fault on one slave branch will never crash the entire SCADA bus.
Product Overview
The Valtoris 4CH-HUB-RS485 is a rugged, industrial-grade 4-Port Isolated RS485 Hub. Engineered to overcome standard RS485 distance and node capacity limitations, it actively repeats and expands your serial network up to an additional 1200 meters per branch. It physically separates each downlink channel, offering unmatched reliability and surge protection for mission-critical automation networks and data acquisition systems.
Quick Specs & Capabilities
- Hardware Interfaces: One (1) RS485 Master uplink port splitting into Four (4) independent RS485 Slave downlink ports.
- Industrial Protection: Equipped with 2500V optical isolation and 12KV electrostatic discharge (ESD) surge protection to block destructive ground loops.
- Adaptive Baud Rate: Plug-and-play intelligent processing automatically synchronizes with your host network speeds from 300 bps up to 460.8 kbps.
- Network Expansion: Functions as an active signal repeater, securely extending the communication distance of each RS485 branch by up to 1200 meters.
- Form Factor: Compact, DIN-rail mountable enclosure (35mm) with intuitive LED diagnostic indicators for instant visual troubleshooting.
