K+S has over 300 fully functional test stands which allows our Technicians the ability to fully system test every PLC repair.
This ability allows us to simulate how the unit will operate within a plant environment so we can check for elevated temperature faults.

We go beyond bench testing with a high-tech approach that includes building test stands in “hot boxes” and dynamically testing your PLC components with the actual controllers, under load, in an environmental condition, just like the factory.
During the PLC repair process we find the faults, correct them, retest the component to verify operation and burn them in for a period of 72 hours.
Brands We Service
Allen Bradley
K+S Services proudly offers qualified PLC repair services for many new and discontinued Allen Bradley PLCs. All repairs are performed by a factory-trained technician in contaminant-free, heat-sealed enclosures and follow our ISO 9001:2015 quality management standards.
Our state-of-the-art facility also features custom-built dynamic test stands for various Allen Bradley PLC models, including our MicroLogix 1500 test stand with a 1764-24AWA base unit and 1764-LSP, LPR processor module, our PLC 2 system with custom-built diagnostic programs to detect and eliminate common system faults, and our CompactLogix stand which can be expanded to meet customer needs. We test and burn PLCs for 2 to 3 days to reduce intermittent failures. Any faulty components are replaced with OEM components, and if we discover any components that are known to fail, we will replace them as a standard precaution.
