Giới thiệu TTL to RS485 Module Mô Đun Điều Khiển Chuyển Đổi B'Chip Ttl Sang Rs485 485 To Serial Uart tại Lotte Market
Product parameters:
1. All the chips are brand new original imported industrial grade chips, which can reach up to kilometer in long distance transmission.
2. ESD protection with plus or minus 15KV
3. The chip has a slew rate driver to minimize EMI and reduce signal reflection caused by improper terminal matching cables, resulting in error-free signal transmission rates up to 500Kbps.
4. Receiver input impedance with 1/4 unit load, support multi-machine communication, allowing connection to the bus of 128 devices.
5. Industrial grade chip can reach -40 ° C to 85 ° C
6. This module can be hot swapped, and there will be no signal embolism caused by hot plugging of other 485 chips.
7. The power supply uses a chip tantalum electrolytic capacitor and uses a double capacitor for high and low frequency power supply filtering.
8. Using dual transient suppression diodes, overvoltage protection is better
9. Use 10Ω current protection resistor, patch design to improve 485 signal performance
10. With terminal and soldering lead holes for easy debugging and fixed wiring, soldering leads can improve signal reliability
11. RS485, TTL signals all single-sided routing, to ensure signal quality, improve signal integrity
12. Large area copper plating to prevent signal interference
13. With 2.54 pitch hole plate welding hole, convenient for your secondary development
14. It has quite common M3 screw holes, which is convenient and reliable to install.
15. With 120Ω termination resistor, short-circuit R16 to enable termination resistor
16. With power supply and RXD, TXD signal indicator, the receiving and receiving status is unobstructed
17. The bent foot pin is taken out for testing
18. Support 3.3V and 5V signal control, more compatible
