- Output Range: Supports voltage (e.g., ±10V) and current (e.g., 4-20mA) outputs, with typical accuracy of ±0.1% of full scale.
- Digital I/O: Equipped with several (e.g., 16) isolated digital input/output channels, supporting TTL/CMOS levels for switch control or status monitoring.
- VME Bus Interface: Compatible with VMEbus Rev. C.1 standard, supporting 32-bit data transmission with a bus speed of up to 40MB/s, ensuring high-speed communication with VME hosts.
- Power Requirement: Typically requires ±5V and ±12V DC power supply (specific parameters refer to the manual), with power consumption adapting to industrial power specifications.
- Operating Environment:
- Operating temperature: 0°C to 60°C
- Storage temperature: -40°C to 85°C
- Humidity: 5% to 95% RH (non-condensing)
- Anti-interference: Features optical isolation and filtering design, compliant with industrial-grade EMC standards, suitable for strong electromagnetic interference environments.
- High-Precision Data Acquisition: 16-bit A/D converters combined with low-noise signal conditioning circuits ensure measurement accuracy over a wide range, meeting precision testing and control requirements.
- Multi-Channel Synchronous Sampling: Supports simultaneous sampling across multiple channels, capturing transient signals or phase-related multi-parameters (e.g., three-phase electrical signals), ideal for dynamic process analysis.
- Flexible Signal Adaptation: Software-configurable to adapt to different input signal types (voltage/current) and ranges, enabling adaptation to diverse scenarios without hardware modifications.
- VME Bus Advantages: Leverages the high reliability and real-time performance of the VME bus, allowing integration with other VME modules (e.g., processors, communication modules) to form distributed control systems for complex industrial logic.
- Diagnostic and Protection Functions: Built-in self-diagnostic circuits monitor module power supply and channel status. Some models include overvoltage/overcurrent protection to prevent damage from abnormal external signals.
- Real-time monitoring of multi-parameters in industrial process control (e.g., acquisition of analog signals such as temperature, pressure, flow).
- Condition monitoring and control of motors and transformers in power systems, collecting key parameters like voltage and current.
- Test benches in aerospace and defense sectors for equipment performance testing and data logging.
- Closed-loop control in automated production lines, driving actuators (e.g., valves, servo motors) via analog outputs.
- Cooperation with VME bus hosts (e.g., VMIVME-7805 processor modules) to build highly reliable distributed measurement and control systems.
- Compatible with VME bus-standard industrial computers or controllers, seamlessly integrating with other VMIVME series modules (e.g., digital modules, communication modules).
- Supports programming and configuration via the VME bus, providing standard drivers and APIs compatible with development environments such as LabVIEW and C/C++, facilitating rapid application development.
- Some models support industrial protocols like MODBUS (with a communication module), enabling integration into SCADA systems for remote monitoring.
With its high precision, reliability, and flexibility of the VME bus, the VMIVME-7614-132 serves as a key component in industrial measurement and control, particularly in scenarios demanding high stability and real-time performance.
