plcsElectronic components are seemingly everywhere in today’s economy. Controllers, PLCs, SCADAs,

feedback devices, and other “smart” components are increasingly

present in your production lines and processes. Ryan Herco and SunSource have the resources, knowledge, and experience to provide you with an economical repair option for these items rather than just scrapping them when they break. We can assist you with:


Electronic Drives

Our Electronics Repair Department specializes in industrial drive components and their applications. We have the expertise and equipment to clean, check and dynamically test your component to replicate its malfunction, and the skilled technicians to fix it. Once the unit is approved for completion it is repaired and load tested on one of our custom-built test stands to simulate your application under working conditions.

We service all major brands including Allen Bradley, Reliance, GE, Fanuc, Indramat, Siemens, ABB, Mitsubishi, Yaskawa and many more.



plcsPLCs have become the nerve center of the modern manufacturing facility, and it only takes one board failure to bring production to a halt. Ryan Herco not only offers emergency repair service but in many cases, we can offer an exchange board for immediate delivery. Whether you have an I/O card, Processor or Power Supply, our standard 3-5 day service covers all major brands of PLCs including: Allen Bradley, GE, Modicon, Texas Instruments, Reliance, Mitsubishi, and Siemens. All PLCs are closed-loop, system tested on a matching rack to ensure a quality repair. 


HMIs, Industrial Computers & Touch Screens

plcsThe convenience of Human Machine Interface control panels has made them indispensable on the plant floor. Unfortunately, they are one of the most fragile components in your entire system. Ryan Herco has a staff of trained technicians who will clean, static check, and test your HMI to evaluate its condition. Upon your approval, we will repair and test your unit. Every HMI repair carries our 1-year Operational Warranty. 


LCD Upgrades

lcd upgradesWe offer energy-efficient LCD display upgrades for your old, bulky, legacy CRT monitors in your facility. We provide expert service to the following brands: Allen Bradley, Eaton, Fanuc, Siemens, Toshiba, Xycom, and more. 



plcsWe have experience with over 150 brands of encoders, pulse coders, pulse generators, resolvers and tachometers. We offer complete electrical and mechanical repair on your encoders with all repairs fully tested and guaranteed.


Welders & Weld Controls

plcsOur certified technicians can repair your welder or weld controller and bring your equipment back up to full OEM specifications. With our load testing capabilities and our attention to detail, we can ensure your unit's peak performance. We provide expert service to the following welder and weld control brands: Miller, Lincoln, Yaskawa Motoweld, ESAB, Panasonic, OTC Daihen, WTC Weltronic, Dengensha, and Robotron. 


Light Curtains

plcsAll light curtains are thoroughly evaluated and rigorously tested by our experienced technicians. After the initial test, every unit is then duration tested for at least 8 hours to verify the proper operation of the unit before it's returned to you. Common brands include: STI, Sick Optic, Banner, Dolan Jenner, and many more. 


Teach Pendants

teach pendantsWhen your teach pendants fail, you need them repaired fast so your vital equipment isn't sitting idle any longer than necessary. We system test every teach pendant repair on the matching robotic controller to ensure proper operation. We stock many replacement membranes, E-stops, and displays for prompt service. 


Power Supplies

powers suppliesA failure in a power supply can stop an entire line. Rely on Ryan Herco to clean, static-check, and load test your power supply. Upon your approval, repair time is usually 10 days or less and emergency service is always available.



Ryan Herco industrial repair has over 20 robotic manipulators and controllers to be able to system test your robotic components. Devices such as teach pendants, servo amplifiers, power supplies, and control boards are closed loop system tested on the exact same type robotic system that you use in your manufacturing process. This allows us to not only verify that the original problem with the unit has been corrected, but to also verify that all other working parameters are correct.

Robotic units we can repair include ABB, Comau, Fanuc, Kawasaki, Kuka and Motoman.

Our robotic fleet is dedicated to test the following:

  • CPU/Power Supplies and I/O Cards
  • Servo Drives/Multi Axis Amplifiers
  • Servo Motors
  • Teach Pendants
  • Wrist Assemblies
