Acromag, Inc. manufactures embedded computing, process instrumentation, and distributed I/O products.

Established in 1957, Acromag built its reputation designing critical measurement instrumentation equipment for the petrochemical and aerospace industries. It has since been a designer of analog and digital control products for the industrial I/O market.

Acromag's experience in designing industrial I/O has paved the way for solutions to ground loops,[1] RFI/EMI noise,[2] and temperature drift.[3] Many products are available with agency approvals such as UL, cUL, FM, CSA, CE, ATEX, and others to assure precise operation in hostile environments.

The company has three product divisions: Embedded Computing Solutions, Process Control and Automation Solutions and Contract Manufacturing Services. Its product lines are aimed at manufacturing, military, scientific, public utility, and transportation applications.


Acromag's history began in 1957 with Henry Patton, a pioneer in the development of solid-state magnetic amplifiers. Expanding from its first location in Detroit, Michigan (now Southfield), Acromag headquarters currently reside in Wixom, Michigan.

It acquired Xembedded, LLC (formerly XycomVME) in 2012.[4]
