Wide voltage supply (3.0V~30V), limit voltage 33V, recommended to use within 30V, the minimum voltage should be higher than 2.8V.

Compatible with 3.3V and 5.0V signals, both can match the module.

Excellent EMC and EMI performance.

Strong anti-jamming ability, and strong 485 lightning protection design, working temperature is - 40 C to + 85 C.

With terminal and silicone wire, it is very convenient to use.

With RXD and TXD signal indicators.

This module fully considers the lightning protection design and anti-interference design of 485 bus. It has very high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. When long-distance transmission in the field, connecting the "earth" end of the module to the earth can play a very good anti-interference and anti-lightning role, making 485 bus safer; indoor short-distance transmission can not access the earth.

With standard 2.54 spacing needle arrangement, it is convenient for your secondary development.

With 120 Euro matching resistance, short R0 can make matching resistance possible, and short R0 is recommended for long-distance transmission.

Supporting multi-machine communication, the same network can connect at least 40 nodes.

Hot plugging can be done without signal blocking.

Anti-interference routing and copper laying to prevent interference of signals.

Description

TTL to RS485 module Hardware automatically flows to the control board, RS485 to TTL signal microcontroller serial port

The power supply of this product is a wide voltage (3.0V~40V), which realizes the compatibility of 3.3V system and 5.0V system, and can match 3.3V and 5.0V signals. This product comes with wiring terminals and silicone wires, which can be directly wired and used. All original imported chips are used, with powerful performance, lightning protection design, strong anti-interference ability, and industrial grade.

This transparent transmission module realizes the conversion between TTL signals and RS485 signals, but everyone must know that 485 is half-duplex communication. This communication method can realize two-way communication, but it cannot be carried out in two directions at the same time, and must be carried out alternately; that is, each section of the communication channel can be a sender or a receiver, but at the same time, information can only be transmitted in one direction.

The module realizes the automatic flow control of RS485 signals and the automatic switching of the receiving and sending directions. Using this module is as simple as operating a serial port.

Baud rate: 110~256000bps

Module features:

(1) This module fully considers the 485 bus lightning protection design and anti-interference design, with extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. When transmitting over long distances in the wild, connecting the "ground connection" end of the module to the ground can play a good role in anti-interference and lightning protection, making the 485 bus safer; it can be disconnected from the ground when transmitting over short distances indoors.

(2) With standard 2.54 pitch pin headers, it is convenient for your secondary development

(3) With 120 ohm matching resistors, shorting R0 can enable the matching resistors. It is recommended to short-circuit for long-distance transmission.

(4) Supports multi-machine communication, and at least 40 nodes can be connected to the same network

(5) Can be hot-swapped, and there will be no signal deadlock

(6) Anti-interference routing and copper laying methods to prevent signal interference
