JETTER JX6 Series Technical Notes

The JETTER JX6 series is a modular programmable logic controller (PLC) platform engineered and manufactured in Germany by Jetter AG. It has established a significant installed base across heavy industrial sectors including chemical processing plants, refinery automation, nuclear facility auxiliary systems, and large-scale manufacturing lines throughout Europe, Asia, and the Middle East. The JX6 architecture is built around a passive backplane (card rack) system, where the JX6-BASIS-8 serves as the 8-slot card rack — the physical backbone into which all CPU, I/O, and communication modules are inserted. Its DIN-rail-compatible form factor and robust backplane bus make it a standard infrastructure component in JX6-based control cabinets. Due to the platform's long deployment history, a substantial number of JX6 installations remain in active production service, creating sustained demand for both new and refurbished spare parts.

The Evolution of JX6 Architecture

Jetter AG introduced the JX6 platform as a successor to earlier relay-based and first-generation PLC systems, targeting mid-to-large scale machine automation and process control. The JX6 architecture is defined by its modular slot-based design: a central card rack (BASIS) accepts interchangeable modules across CPU, digital I/O, analog I/O, and fieldbus communication categories. Early JX6 deployments used proprietary Jetter bus communication between the CPU and I/O modules via the backplane. Later revisions introduced support for CANopen and PROFIBUS-DP fieldbus adapters, extending the platform's integration capability with third-party field devices. The JX6 series has entered its mature/end-of-life phase; Jetter AG has transitioned its current product portfolio toward the JX3 and JetWeb platforms. However, the JX6 remains in active service at thousands of installed sites globally, and original spare parts — particularly card racks, CPUs, and I/O modules — are no longer manufactured in volume, making secondary market sourcing critical for plant maintenance teams.
