RS485 Hub Auto?Sensing Multi Port Hub Optical Isolation for Allocate Bandwidth
Feature:
1. The hub can prevent bus failure and damage caused by the voltage difference between the power supplies at both ends of the master and slave.
2. This RS485 hub can be optoelectronic isolated, automatically sensed, stable performance, and high?speed transmission.
3. Safety protection, signal port with reverse connection, short?circuit alarm indication and can automatically isolate faulty channels.
4. The internal processor chip can automatically identify and control the data direction without external intervention.
5. Using industrial-grade quality, the core chips are all imported with original packaging, which is stable and durable.
