Dual transceiver ensures robust communications with lower power for Industry 4.0 applications

Designers of Industry 4.0 applications can now achieve robust communications and reduce power dissipation by 50% with the MAX14819 dual-channel, IO-Link master transceiver from Maxim Integrated Products. Today’s fanless programmable logic controller (PLC) and IO-Link gateway systems must dissipate large amounts of power depending on IO configuration (IO-Link, digital input/output, analog input/output). As these PLCs evolve into new Industrial 4.0 smart factories, special attention must be considered to achieve smarter, faster, and lower power solutions while also meeting IO-Link and standard IO (SIO) compliance. Maxim continues to provide a portfolio of advanced factory automation solutions that creates pathways toward achieving Industry 4.0. The unique architecture of the MAX14819 dissipates 50% less heat compared to other IO-Link Master solutions and is fully compatible in all modes for IO-Link and SIO compliance. Robust L+ supply controllers with settable current limiting and reverse voltage/current protection help ensure robust communications with the lowest power consumption. With just one microcontroller, the integrated framer/universal asynchronous receiver-transmitter (UART) enables the most scalable and cost-effective architecture while enabling the industry’s fastest cycle times (up to 400 microseconds) and reducing latency. The device is available in a 48-pin (7mm x 7mm) TQFN package and operates over the -40C to +125C temperature range. Applications include IO-Link master systems and IO-Link gateways.
