1. [1 in 8 Out] This hub adopts 1 channel 485 input, 8 channel 485 output, each channel is isolated and supports up to 128 nodes.
2. [Powerful Robustness] The built in optoelectronic isolator and 600W guard circuit can provide isolation guard of up to 2500Vrms, effectively suppressing ESD, while also preventing strikes and common ground interference.
3. [Automatic Switching] This 485 hub can automatically switch enable control circuit to easily solve the delay problem of 485 transfer and reception conversion.
4. [Short Open Circuit Guards] Each port has short circuit and open circuit guard, allowing users to easily improve the 485 bus structure, segment network segments, and isolate fault channels.
