12Pcs MAX485 RS485 Transceiver Module - Review

As a professional product reviewer and an expert in SEO, I had the opportunity to try out the DORHEA MAX485 RS485 Transceiver Module for TTL UART Serial to RS485 Instrument Interface Module. In this review, I will provide an in-depth analysis of this product and its features.

Firstly, the MAX485 chip is the main component of this transceiver module and it is very energy efficient, drawing only between 120µA and 500µA. This makes it an economical and cost-effective choice for users who need to communicate over long distances. Additionally, it also limits the slew rate transceiver, which enables serial communication over very long cable runs up to 4000 feet/1200 meters. This is a significant advantage for users who need to transmit data over long distances without signal loss or interference.

The 5.08 mm pitch 2P terminal is another one of its convenient features for RS-485 communication wiring. Chip leads control all pins through a microcontroller, which provides users with more control over their data transmission. Moreover, this RS485 transceiver module can transmit serial data in both directions (half duplex) at a data rate of up to 2.5Mbps. This speed is ideal for high-data applications, such as industrial control networks.

Users can also connect multiple modules together for communication between two or more devices (up to 32). Additionally, two modules can be configured as a repeater for even greater distances. This makes the RS-485 module an ideal choice for industrial control local area networks, level translators, transceivers for EMI-sensitive applications, low-power RS-485 transceivers, and low-power RS-422 transceivers.

The product is easy to use with the standard 0.1” pitch header pins provided for data connections. These pins can also be soldered into standard prototyping PCB and breadboards. Furthermore, screw terminals provide conventional connections to the actual data cable, which increases the durability of the connections.

The MAX485 chip drivers are short-circuit current limited, which is an important feature as it protects against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input also has a fail-safe feature that guarantees a logic-high output if the input is open circuit.

However, it is important to note that this product might not be suitable for all users. According to its customer review stars, it has received a 3.9 out of 5 star rating with fifteen reviews. While the product has multiple benefits, there still may be some limitations that some users have to encounter.

In conclusion, the DORHEA MAX485 RS485 Transceiver Module is an excellent choice for users who need to transmit data over long distances with minimal signal loss. Its energy-efficient and easy-to-use features make it a cost-effective and reliable choice for industrial control networks and other applications. However, it is important to note that it may not be suitable for all users and hence, proper research must be conducted to determine if this product is suitable for certain individual needs.
