Industrial Control

We Specialize in the Repair
and Refurbishment of Industrial
Control Components
Galco Industrial Electronics specializes in the repair and refurbishment of Industrial Controls from hundreds of manufacturers. Since 1975 our technicians have been repairing Industrial Controls and other industrial electronic equipment including Circuit Boards, Drives/Motors, CNC/Robotics, Power Control Equipment, Test Equipment, and many others.
Industrial control components are the brains of a modern automation environment, coming in all shapes and sizes and performing a variety of functions.

Identifying a Fault in
the Industrial Control Component
Industrial control components serve as the backbone of many modern automated systems. They have an extended range of capabilities that can perform many useful control functions: relay logic, counting, timing and sequencing functions, and even complete control of individual machines or complex processes through input and output functions. Because of their critical union with industrial equipment, PLCs, HMIs, Controllers and Starters, and the I/O modules that serve them are often found and used in harsh environments. When troubleshooting industrial control components, it is important to look beyond the components themselves. Their delicate place in an industrial control network means receiving, or not receiving, input from any number of external components that may be at fault.
Common Industrial Control Faults

No Output or No Display

Common output and display problems on HMIs and PLCs can be attributed to faulty connections. Check for proper power connections and any obvious signs of damage. External devices may also be at fault, if the industrial control device isn’t receiving any input.

Program Errors

Power, grounding, and interference problems can all cause the corruption of the PLC memory. A PLC can lose its program during power outages or large interference events like a large motor starting or arc welding in the area. Verify your program is correct with a backup, and reload if any problems are encountered.

Unresponsive Controls

Control panels may become unresponsive because of their use in harsh industrial environments. If the component uses physical controls, the issue is likely internal – a loose connection or misaligned contact. Touch controls may require recalibration.
