The MTS Systems FlexTest GT Digital Controller is a modular, high-performance control platform for advanced materials testing. It delivers real-time closed-loop control, multi-channel data acquisition, and transducer conditioning across distributed test stations. The system architecture supports flexible reconfiguration without hardware or cabling modifications, enabling rapid test setup changes and accommodation of diverse specimen behaviors.
Technical Specifications
• Chassis: Model 493.10 with support for up to 32 modules across 8 channels and 4 stations, or up to 6 stations
• I/O Configuration: Multiple I/O Carrier Boards (Model 493.40) each accommodating four mezzanine cards
• Power Requirements: 100–240 VAC, 50/60 Hz, 5–10 A
• Channel Assignment: Any input assignable to any control channel; control channels allocable to any test station
– Key Features
• Real-time closed-loop control with PIDF (proportional, integral, derivative, feedforward) algorithms
• Adaptive control compensation and cascade control capabilities
• Calculated channels for derived measurements
• Digital and analog signal conditioning via mezzanine card architecture
• Support for specialized conditioners: Digital Universal Conditioners (Models 493.21B, 493.25); Valve Drivers (Models 493.14, 493.15); A/D and D/A converters (Models 493.45, 493.46); Encoder conditioning (Model 493.47); Acceleration conditioning (Model 493.48); Analog filtering (Model 493.77 Filter Input 300 Hz)
• User-programmable digital inputs and outputs
– Typical Applications
Multi-station materials testing environments requiring precise control over non-linear or changing specimen behavior. Suitable for both laboratory and industrial test facilities.
– Compatibility & Integration
Mezzanine card support enables integration of hydraulic valve control, analog signal processing, encoder feedback, acceleration measurement, and analog filtering functions. Modular I/O architecture supports expansion and field reconfiguration.
