Description

1. ESD protection with positive and negative 15KV
2. The chip has a limited swing rate driver to reduce EMI and signal reflection caused by inappropriate terminal matching cables, thus making the signal transmission rate of zero defect up to 500 kbps.
3, with 1/4 unit load of the receiver input impedance, support multi-machine communication to is not more than 128 devices on the bus.
4, industrial chip operating temperature can reach-40 ℃ to +85 ℃.
5. This module can be hot-swap, and there will be no signal plug-in phenomenon hot-swap other 485 chips.
6. The power supply uses a patch-on-aluminum electrolytic capacitor, and uses double capacitors for high and low frequency power supply filtering.
7. Excellent overvoltage protection performance with dual transient suppression diode
8.Using 10Ω current protection resistor,chip design improves 485 signal integrity
9.It has terminals and welding lead holes,which is convenient for debugging and fixed wiring,and welding leads can improve signal reliability
10.RS485 and TTL signals are all single-sided to ensure signal quality and improve signal integrity
11.Large-scale copper laying to prevent signal interference
12.It has a 2.54 pitch hole plate welding hole,which is convenient for your secondary development
13.It has the M3 screw hole that is quite commonly used at present,which is convenient and reliable to install
14. With 120Ω termination resistance,short connection R16 can enable the termination resistance
15. With power supply and RXD,TXD signal indicator light,the transmission and reception status can be seen
16. The angled pin is led out,which is convenient for testing
17. Support 3.3V and 5V signal control,strong compatibility
