TTL Serial Port to RS485 Converter Board Module

TTL Serial Port to RS485 Converter Board Module

TTL To RS485 Converter Module is TTL to RS485 module or RS485 to TTL signal with single-chip serial port and UART. It has lightning protection hardware and automatic flow direction control With RXD, TXD Indicator Lights. 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. This product is equipped with wiring terminals and silicone wire, used for direct wiring.

Features

• 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.
• This module fully considers the 485 bus lightning protection design and anti-interference design.
  
• 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

Specifications

• Wide voltage power supply (3.3V to 30V), with a suggested operating range of 30V and a maximum voltage of 33V. The voltage should be greater than 2.8V.
• Able to match the module with both 3.3V and 5.0V signals.
• High performance in terms of EMC and EMI.
• It uses a potent 485 lightning protection design and has great anti-interference capabilities. - 40 °C to + 85 °C is the operating range.
• It is very easy to use because it comes with a termination and silicone wire.
• TXD signal indicator with RXD
• Baud Rate : 110 to 256000bps
