QuantumX 8‑channel Analog Output Module

MX878B – High Performance in Structural and Mechanical Tests

MX878B is an eight‑channel analog voltage output module designed for dynamic testing and test bench integration. It converts measured values and calculated results from your QuantumX system into precise ±10 V output signals, enabling realistic stimulus profiles, setpoints, and control interfacing in durability tests and continuous fatigue life investigations. With real-time computations performed directly in the module, MX878B adds real functionality to your test system.

Key features

• Eight galvanically isolated, individually configurable analog outputs
• Scalable voltage outputs from 10 to 30 V (24 V nominal (rated) voltage)
• 16‑bit resolution
• Output of module inputs or calculated signals for flexible stimulus generation
• Real-time calculations include: algebra, rms, add & multiply, peak-value, matrix computation and PID (proportional integral derivative) control
• Integrated signal generator supplying harmonic or arbitrary waveforms
• BNC connectors for robust lab-grade wiring
• Connections:
  • 1 x Ethernet with PTP support
  • 2 x FireWire
• Voltage supply: 10 to 30 V DC, max. 7 W

Flexible outputs for truly dynamic testing

MX878B transforms measured sensor values, such as force, strain, pressure and temperature, directly to a voltage signal. The measurement quantities or signals (CAN) are acquired in real time and sent to MX878B as digital values. They can be, if desired, set off against each other, and then output as analog voltage signal in the range of ±10V.

In the case of durability tests, the measured sensor values can be transformed into proportional output voltages, combined in real time, or fed through PID control to generate load and setpoint profiles.

Typical applications

• Durability and fatigue testing in automotive, aerospace, rail, and structural engineering
• Stimulus and setpoint generation for servo-hydraulic or electromechanical benches
• Converting sensor measurements into analog control signals for legacy systems
• Real-time computed outputs for multi-channel dynamic experiments
• Laboratory development where repeatable waveform outputs are required

Expand your system capabilities

MX878B integrates into the QuantumX universal data acquisition system providing not only analog voltage outputs but also real-time functions that upgrades connected modules such as Universal Amplifier MX840B. When digital inputs or outputs are required in addition, the Multi I/O Module MX879B can be used. Ethernet with PTP keeps outputs aligned with acquired sensor data, while FireWire provides straightforward expansion for scalable channel counts.

MX878B is supported by HBK catman^® Easy/AP software for setup, visualization, and analysis. It also fits into automated environments via support for LabVIEW™, Microsoft Visual Studio^® .NET, CANape^® and DIAdem.
