II. Core Functions and Features

(1) High-speed Sampling and High-Resolution Conversion

Built-in 16-bit A/D converter, providing 12-bit effective resolution, balancing conversion speed and measurement accuracy;

Single channel maximum throughput rate of 100kHz, fast conversion rate, capable of accurately capturing high-frequency dynamic signals such as vibration and transient pressure;

Fixed calibration parameters at factory, stable long-term use accuracy, reducing on-site calibration and maintenance costs.

(2) Flexible Channel Configuration

Supports two input topologies, suitable for different on-site anti-interference and wiring requirements:

32 single-ended input: suitable for common ground and low interference scenarios, maximizing the number of channels;

16 differential input: strong anti-common-mode interference, suitable for long-distance transmission, strong electromagnetic interference environments (such as motor workshops, high-frequency equipment surroundings).

(3) Large-capacity Onboard Cache, Reducing Bus Pressure

Integrated 64KB dual-port sample RAM, capable of storing over 32,000 sampling points, no need to frequently occupy the VME bus during high-speed acquisition, avoiding bandwidth bottlenecks;

Equipped with 256-byte sequence RAM, supports programmable custom channel sampling sequence, can flexibly arrange the acquisition sequence of non-continuous channels, suitable for complex multi-channel synchronous/asynchronous acquisition processes.

(4) Independent Programmable Gain for Each Channel

Provides 12 levels of programmable gain, independently configuring gain for each channel through dedicated gain RAM;

Gain range covers 1x to 100x, capable of amplifying weak sensor signals such as strain gauges and thermocouples, or attenuating strong amplitude voltage signals, suitable for different amplitude inputs, without the need for additional signal conditioning modules.

(5) Multiple Trigger Modes and Programmable Clock

Three startup acquisition trigger methods: onboard clock trigger, external hardware trigger, software trigger, suitable for synchronous acquisition, event trigger acquisition, manual control acquisition, etc.;

Built-in programmable sampling clock, can precisely set sampling rate (up to 100kHz), flexibly matching the frequency characteristics of different signals;

Supports VMEbus standard interrupts and programmable interrupt timers, triggering interrupts when conversion is completed or when the buffer is half full/full, achieving real-time data processing and event response, improving system efficiency.

(6) Standard VME Bus Compatibility and Industrial-grade Reliability

Fully complies with VMEbus standard specifications, 6U dual-slot (Double) VME board card structure, supports hot plugging, can seamlessly integrate into various VME bus industrial control systems;

Industrial-grade wide temperature design, operating temperature 0°C to 55°C, storage temperature -40°C to 85°C, tolerant of harsh industrial environments;

Low power consumption design, conforms to VMEbus standard power supply (+5V), suitable for high-density rack deployment;
