The PCS8000 is the 4th-generation flagship digital controller from walter+bai ag, designed as the central measurement and control brain for materials and component testing laboratories. It serves electromechanical, servohydraulic, and electrodynamic testing machines, executing monotonic through high-cycle fatigue tests with a closed-loop control rate of up to 14.4 kHz — fast enough to catch dynamic events that slower controllers miss.

What makes the PCS8000 modular and expandable?

Each PCS8000 unit provides up to 12 analog input channels with 24-bit resolution plus a dedicated digital stroke channel onboard. Multiple controllers can be interconnected to scale the system to complex multi-axis test rigs with up to 200 independent control loops. Each loop can regulate force, displacement, deformation, strain, or a calculated virtual channel combining multiple physical inputs — enabling advanced test profiles such as cross-coupling compensation and simulated service loads.

How does the controller handle different types of testing machines?

The PCS8000 is universal across testing machine types. It drives electromechanical screw-driven frames for quasi-static tensile and compression tests, servohydraulic actuators for high-force dynamic fatigue, and electrodynamic shakers for vibration testing — all from the same controller hardware. The 64-bit 1 GHz processor and Ethernet/LAN PC interface ensure deterministic timing independent of the host computer operating system, eliminating jitter in long-duration creep or stress relaxation tests.

What software ecosystem supports the PCS8000?

The controller integrates with walter+bai's DION 7 testing software suite, which provides test definition, real-time data visualization, analysis, and reporting for standard and custom test methods. DION 7 handles everything from simple monotonic tensile tests to complex multi-axis block loading programs with automated report generation. The Ethernet interface allows the controller to be located close to the test frame — reducing transducer cable length and electrical noise — while the operator PC resides at a control desk.
