Module Features:
1, All the chips we guarantee is a new original industrial grade chip, ultra-long-distance transmission up to kilometers.
2, With positive and negative 15KV ESD protection
3, The chip has a slew rate driver, effectively reduce EMI, and reduce the signal caused by improper termination of the cable reflection, so that error-free signal transmission rate up to 500Kbps.
4, With 1/4 unit load receiver input impedance, support for multi-machine communication, allowing access to 128 devices on the bus.
5,Industrial chip operating temperature can reach -40 ℃ to +85 ℃.
6,The module can be hot-swappable, there will be no other 485 chip hot plug signal appears to bolt dead.
7, Power chip tantalum electrolytic capacitors, and dual capacitors for high and low frequency power supply filter.
8, The use of dual transient suppression di
