Industrial 2-Ch Cache-type RS485 Hub, Wide Baud Rate Range, 2 master and 1 slave / 1 master and 2 slaves
$28.99
💡 Zero Collision Hardware Cache & Independent Channels
The 2CH-HUB-RS485 prevents RS485 bus congestion with an active hardware cache, unlike conventional signal repeaters. It automatically routes data between multiple masters and slaves without collision, even when connected legacy devices operate at different baud rates.
Product Overview
Valtoris 2CH-HUB-RS485 is a special Industrial Cache-Type RS485 Hub. It is designed for complex multi-host routing topologies and supports flexible 2-master/1-slave or 1-master/2-slaves polling configurations. It actively buffers simultaneous data requests, eliminating the timeout errors and data collisions that plague traditional daisy-chain SCADA networks.
Quick Specs & Capabilities
- Hardware Interfaces: 2 independent RS485 channels utilizing standard 3-pin pluggable screw terminals for fast field wiring.
- Zero Collision Polling: Built-in memory cache actively queues and dispatches simultaneous SCADA requests to guarantee data integrity across the bus.
- Adaptive Port Configuration: Each channel operates autonomously, supporting customizable baud rates ranging from 1,200 up to 460,800 bps.
- Industrial Protection: Equipped with robust internal overcurrent protection circuits and easily replaceable fuses to block destructive voltage spikes.
- Form Factor & Management: Compact design supporting 35mm DIN-rail installation, complete with a visual Windows utility for advanced parameter configuration (address masks, whitelists).
