Process Controls

Merlin® Controls has been providing embedded microprocessor process control systems since 1985. If you have a requirement for more than 5 similar controls a year, we can save you programming and design monies. FMDK can offer software and hardware development based on yearly commitments. Private labeling is also fully supported. Control panel assembly and final test may be maintained at your facility or we can provide the complete package. Our expertise allows us to be very competitive with small system requirements.
