TTL to RS485 Power Supply Converter Board 3.3V 5V Hardware Auto Control Module
This TTL to RS485 Module provides seamless conversion between TTL signals and RS485 signals, making it suitable for use with single-chip serial ports, UARTs, and devices requiring lightning protection. The module supports automatic flow control, with the ability to switch between transmission and reception modes without manual intervention.
With a wide voltage range of 3.0V to 30V, it is compatible with both 3.3V and 5.0V systems, ensuring flexibility for various applications. The module features convenient wiring terminals and comes with silicone wires for easy connections.
Built with high-quality imported chips, the module offers robust performance, lightning protection, excellent anti-interference capabilities, and industrial-grade reliability. It also includes a one-year warranty. Simple to operate, this module functions much like a standard serial port, making integration straightforward for your projects.
Features
- This module fully considers the 485 bus lightning protection design and anti-interference design.
- It has extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance.
- When long-distance transmission in the field, the module is connected to the earth Access to the earth can play a good role in anti-interference and lightning protection, making the 485 bus more secure; the indoor short-distance transmission can not be connected to the earth.
- With standard 2.54 pitch pin headers for your secondary development
- With 120 ohm matching resistance, short-circuit R0 to enable matching resistance, short-circuit is recommended for long-distance transmission.
- Support multi-machine communication, at least 40 nodes can be connected to the same network
- It can be hot-swapped and there will be no signal thrombosis
- Anti-interference wiring and copper laying method to prevent signal interference
