This product through the use of a high quality with isolated characteristic chip, to achieve the perfect isolation TTL,
RS485 signal on both sides of the power and signal, super anti-jamming capability. Wide power supply range (3.0V ~ 5.5V), to achieve the perfect system compatible with 3.3V and 5.0V systems, 3.3V or 5.0V level can match. All using imported chips, absolute industrial design,
This module implements mutual conversion between TTL signals and RS485 signals, but we must know that the 485 is a
half-duplex communication, this communication can be two-way communication, but not both simultaneously in both directions ,
you must take turns alternately; That is, each section of the communication channel can be sending end, the receiving
end may be, but at the same time, the information is only one direction of transmission.
The perfect realization of the automatic flow control RS485 signal, the transceiver automatically switches direction.
You use this module with the same serial operation simple.
Baud rate: 110 ~ 256000bps
Highlights:
(1) Wide voltage power supply (3.0V ~ 5.5V);
(2) communication signals compatible with 3.3V and 5.0V level, can match the module;
(3) power supply and signal completely isolated, high EMC and EMI performance, isolation voltage up to 2500V DC;
(4) Absolute using imported chips, industrial grade design, excellent robustness, while using more powerful lightning protection design, can be used in the industrial field and harsh outdoor environments, the working temperature of -40 ° to +85 °, the transmission distance of up to 1 kilometer (nearly 1 kilometer transmission distance, please add repeater);
(5) semi-hole process design, thickness of 0.8mm, can be used as TIM and main board, also solderable terminals use;
(6) having RXD, TXD signal lights;
(1) This module fully into account the 485 mine design and anti-jamming design, the use of isolated chips to achieve the power and signal isolation, with bus isolation and protection features, high EMC (electromagnetic compatibility), EMI ( electromagnetic interference) performance. In the wild long-distance transmission, the module "earthed" side to earth, can play a very good anti-interference and lightning effects, making 485 more secure; you can not connect with the ground when the indoor short-distance transmission.
(2) using the standard 2.54 pitch design, easy secondary development.
