TTL to RS485 Level Conversion Module (Red Version)
It is well known that programming the direction control for 485 signals is quite challenging, especially in scenarios involving unknown communication data protocols. When you don’t know the data volume of each packet, you can’t determine when to switch between transmitting and receiving directions. In such cases, you can choose our store’s 485 automatic direction control module to solve these troubles.
This module comes with protection features that offer exceptional value for money – you can compare it with other 485 control modules.
This TTL to 485 automatic direction control module uses MAXIM’s 485 chips with integrated automatic transceiving functionality. We guarantee that every chip is brand-new and original, making it safer and more reliable than other automatic direction control methods (please refer to the detailed parameters below for specifics, which are absolutely unmatched by other 485 automatic direction control modules).
It is recommended to power the module with 5V (since the 485 signal level range is 2-6V, using 3.3V power supply will reduce reliability for long-distance transmission). However, the module can be controlled by both 3.3V and 5V signals (Note: 5V power supply with 3.3V signal control is fully supported, as we have implemented signal protection measures for your peace of mind).
If you have strict requirements for signals, this module is your ideal choice. It features automatic direction control with a maximum baud rate of 500Kbps, and can automatically recognize baud rates below 500Kbps without manual intervention.
Features of TTL to RS485 Level Conversion Module (Red Version)
1. We guarantee that all chips are brand-new, original imported imported industrial-grade chips, with ultra-long-distance transmission capability of up to thousands of meters.
2. Equipped with ±15KV ESD protection.
3. The chip features a slew rate limited driver, which minimizes EMI and reduces signal reflections caused by improperly terminated cables, enabling error-free signal transmission rates up to 500Kbps.
4. With a receiver input impedance of 1/4 unit load, it supports multi-machine communication and allows connection to a bus with up to 128 devices.
5. The industrial-grade chip can operate within a temperature range of -40°C to +85°C.
6. This module supports hot-swapping without the signal latching issue that occurs with other 485 chips during hot-swapping.
7. The power supply uses chip tantalum electrolytic capacitors, with dual capacitors for high and low frequency power filtering.
8. Utilizes dual transient voltage suppressor diodes for superior overvoltage protection performance.
9. Incorporates a 10Ω current protection resistor, with a chip design that improves 485 signal integrity.
10. Features terminals and welding lead holes for convenient debugging and final version wiring; welded leads can enhance signal reliability.
11. All RS485 and TTL signals are routed on a single layer to ensure signal quality and improve signal integrity.
12. Large-area copper cladding to prevent signal interference.
13. Equipped with 2.54mm pitch perfboard welding holes for easy secondary development.
14. Has the currently commonly used M3 screw holes for convenient and reliable installation.
15. Includes a 120Ω termination resistor; shorting R16 enables the termination resistor.
16. Equipped with power, RXD, and TXD signal indicators for clear visibility of transmission and reception status.
17. Right-angle pins are led out for easy testing.
18. Supports 3.3V and 5V signal control for stronger compatibility.
