RS-485 Module Slips Into Industry 4.0 Apps

Maxim Integrated Products’ MAXM22511 2.5kV isolated RS-485/RS-422 module transceiver with power brings intelligence to the edge of typically noisy industrial environments. The module promises to dramatically simplify and shrink the design of field bus communications systems for factory automation, motor control and other industrial internet of things (IoT) applications.


Full industrial convergence calls for intelligence at the edge of the automated factory to enable self-diagnostic and autonomous capabilities. To actively monitor and communicate real-time health and status information required by these environments, factory subsystems demand field bus communications systems that meet stringent size and power efficiency requirements while supporting operations in noisy industrial environments. The MAXM22511, the first in a family of isolated communications ICs, addresses these challenges while simplifying field bus communications system designs. The module accomplishes this by eliminating the need for discrete digital isolators, transceivers, transformers and transformer drivers.

The MAXM22511 supports 25-Mb/s data rates while providing 60% dc/dc efficiency and ±35-kV electrostatic discharge protection. The module is available in a land grid array (LGA) package (9.35mm x 11.5mm, which is 35% smaller than competitive solutions). 


Pricing is $7 each/1,000. Also available, the MAXM22511EVKIT# evaluation costs $125. Of course you can gain even higher altitudes of knowledge by consuming the MAXM22511 datasheet.
