TTL to RS485 Power Supply Converter Board 3.3V 5V Hardware Auto Control Module
TTL to RS485 module, RS485 to TTL signal, single-chip serial port, UART, lightning protection hardware, automatic flow direction control The power supply of this product is wide voltage (3.0V ~ 30V), which realizes the compatibility between 3.3V system and 5.0V system, and both 3.3V and 5.0V signals can be matched.
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 ohms 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
Specifications:
- Operating Voltage (VDC): 3 ~ 30
