We Deliver Products Optimized for Safety, Reliability, and Long Service Life

Relcom has been designing and manufacturing electronic equipment for the Process Control Industry for over 30 years.  We know how to design products that will be deployed in the harsh industrial environments of Oil & Gas, Chemical, Waste Treatment, and other process environments. 

Our customers require long equipment life, typically 10+ years. Long term availability is also required (unlike consumer electronics) so customers can purchase replacements - or expand their systems - for many years to come. Most of the products we design are also certified for use in hazardous areas. North American, ATEX, IECEx, and CCC certifications allow our products to be installed in hazardous areas around the world. 


Our design, development and manufacturing engineering process covers all phases of product development including concept, architecture, detailed turnkey design, testing, and manufacturing. 


We have a team of engineers with the knowledge and desire to help our customers reduce product design costs, improve quality, and drive innovation throughout the product design life cycle.  We can help you realize your product development goals.
We can redesign products that have component obsolescence issues using current parts.  In some cases we can reduce costs increase performance, and improve reliability at the same time.


Our fully equipped manufacturing facility allows in-house product assembly without having to subcontract portions of the manufacturing. This enables very responsive and flexible scheduling for both production and prototype builds.

If you are looking for a partner to design and manufacture an industrial process control electronic product, give us a call or send us an email!
