Designers can quicken troubleshooting and communicate over larger networks with Maxim’s MAX33012E CAN bus transceiver and MAX33072E RS-485 half-duplex transceiver.

These devices are designed to increase industrial system uptime for factory-floor networks. The MAX33012E features the industry’s most advanced fault detection and reporting, while the MAX33072E provides the ability to connect the broadest range of disparate nodes, increasing reliability by enabling the connection of nodes with large ground differences.

Reliable connectivity is essential to optimizing operation and improving system uptime in manufacturing for many critical industrial applications, such as asset management systems and communication fieldbus modules.

MAX33012E: Overvoltage, overcurrent and transmission error faults in CAN will shut down production and idle expensive machinery. To overcome this challenge, the MAX33012E features fault detection on data lines CANH and CANL for overvoltage, overcurrent and transmission failure, as well as fault code reporting. The MAX33012E’s detection and reporting enable the fastest troubleshooting of these faults so vital links can be immediately re-established.

MAX33072E: Modern industrial and manufacturing systems require high common mode voltage tolerance to communicate between disparate systems. The common mode range (CMR) of the MAX33072E is 1.6x greater than that of the closest competitor (receiver only). With the ability to connect the broadest range of disparate nodes, it expands communication network size to allow more machines to operate across larger areas, with simple and reliable links. The MAX33072E CMR of ±40V enables industrial systems to connect and communicate in environments of greater electrical noise, up to where a difference of either -40V or +40V between two nodes is present.

“Automated manufacturing centers are made to run all day, every day to maximize productivity and boost return-on-investment,” said Colin Barnden, principal analyst at Semicast Research. “The ability to solve problems quickly and get production rolling again after equipment goes down is a highly desirable feature for any production environment.”

“Improving uptime in industrial communications is a high priority for industrial system designers,” said David Andeen, executive director for the Core Products Group at Maxim Integrated. “Any time equipment is shut down to look for faults, manufacturers potentially lose revenue. But finding faults more quickly can reduce repair intervals, and these new transceivers help reduce the time that machines sit idle.”
