Greenlight has responded to specific requests for a compact, accurate, flexible, high voltage data acquisition system, as these combined attributes were not available from leading I/O suppliers.  The DAQ2 is the result of two years of product design and testing by Greenlight’s in-house development team.

The DAQ2 enables:

• collection of precise process testing data, such as cell voltage, temperature, current, pressure, and flow
• testing at exceptionally high common-mode voltage
• increased accuracy compared to the first generation model

Specific features:

• Each 2U 19” rack box system has space for four modules (custom form factors are available)
• Each module contains 32 available slots for Analog Front End (AFE) channels equipped with 16-bit A/D converter
• Modules can be configured in a daisy-chain (up to 32 Channels), differential mode (up to 16 Channels), or mixed configuration
• Each slot supports numerous AFE types, including: ± 100mV, ± 5V, ± 10V, ± 75V, ± 150V, ± 300V, 0-20mA, Thermocouple (K, J, S, T types)
• Max channel-to-channel common mode voltage isolation: 1,000VDC
• Channel input impedance (Voltage AFE’s) : ≥1MΩ
• Channel accuracy: ± 1mV with ± 5V  AFE type configuration
• Each module can be connected in a star Ethernet network configuration for 1,000+ channels
• Simultaneous data sampling on each board – not multiplexed
• 1kHz burst sampling mode possible via external trigger input
• Up to 100 Hz continuous data sampling
• Communication interface: 10/100 Mbps Ethernet (optional CANbus)
• Thermal drift compensation on each channel maintains accuracy over wide temperature range
