Features
1、Use isolated chips to achieve isolation of power and signal, with isolation and bus protection functions.
2、Very high electromagnetic compatibility and electromagnetic anti‑interference performance, can play a good role in anti‑interference and anti‑thunder protection.
3、Adopt standard 2.54 pitch design to facilitate your secondary development.
4、With 120Ω matching resistance, short‑circuit RO can match resistance, short‑circuit is recommended for long‑distance transmission.
5、Support multi‑machine communication, at least 128 nodes can be connected to the same network.
6、Hot-swappable, anti-interference wiring and copper laying methods can be used to prevent signal interference.
