TTL To RS485 Hardware Automatic Control Converter Module

It is a TTL To RS485 Module/Converter Module, Operating voltage range: DC 3.0V ~ 30V, Baud rate: 110 ~ 256000bps, has a very high EMC and EMI performance. support multi-machine communication, the same network can connect at least 40 nodes. can be hot-plugging, there will be no signal plug phenomenon.

Parameters:

• Operating voltage range: DC 3.0V ~ 30V
• Operating temperature range: -40 °c to +85 °c
• Baud rate: 110 ~ 256000bps

Module Highlights:

• (1) wide operating voltage range DC 3.0V ~ 30V, the limit voltage is 33V, it is recommended to use within 30V, the minimum voltage is higher than 2.8V.
• (2) compatible with 3.3V and 5.0V signals.
• (3) has a very high EMC and EMI performance.
• (4) using imported chips, industrial design, anti-interference ability, and with powerful 485 lightning design, can be used in harsh environments, such as industrial, field; operating temperature range is -40 °c to +85 °c, transmission Distance can be up to kilometers (test with 850 meters of 2 * 1.5 cable, it is recommended to use within 800 meters, more than 800 meters please add repeaters).
• (5) with a terminal block and silicone wire, the use of very convenient.
• (6) equipped with RXD, TXD signal indicator, convenient to know the send and receive situation.

• (1) the 485 bus is with lightning protection function, with high EMC, EMI performance. When using for long-distance transmission in the field, the module EARTH side please connect to the ground, can achieve well anti-interference and lightning protection function; for indoor short-distance transmission, it cannot connect to ground.
• (2) with standard 2.54 pitch pin
• (3) to enable the built-in 120 ohm termination resistor then, short R0 on the last module on the RS485 line and we would recommend shorted for long-distance transmission.
• (4) support multi-machine communication, the same network can connect at least 40 nodes.
• (5) can be hot-plugging, there will be no signal plug phenomenon.
• (6) using alignment and copper to prevent signal interference.

Package Includes:

• 1 x  TTL to RS485 Signal Converter Module
• 1 x 2.54 White Socket with 4P Lines
