Overview

The DAQ516 is a 16-channel multiplexed signal conditioning system with a 16-bit resolution ADC and 10 BaseT Ethernet connectivity to a PC or laptop for setup, data display and processing. The ultra-compact 57.5mm (2.26″) high, 112mm (4.41″) wide, 220 mm (8.66″) deep fully enclosed chassis weigh just 1.09kg (2.4lbs), making them suitable for in-vehicle applications. The DAQ516 chassis can be powered from DC voltage sources ranging from 10-18 volts. Power consumption is 10 watts for typical configurations, 30 watts maximum. Local data storage is available via a CompactFlashT module. Auto configuration on power-up provides stand-alone capability and along with the simple user interface makes data collection and storage a two-mouse click process.

The signal conditioning consists of 16 multiplexed differential input analog channels that can be configured with fixed 2-pole filters and fixed gains of 1/3 to 100. Filter options are available in a 1,2,5 progression from 10Hz to 1kHz. Filters and gain are configured in 8-channel groups. Input voltage ranges up to ±30 volts are supported. Channel inputs have over-voltage protection of ±35 volts. End-to-end channel calibration is accomplished by configuring the input multiplexers via software to receive a reference voltage provided by an internal calibrator.

Two channels of Frequency Measurement are provided. These channels can alternately be configured as counter inputs. External trigger input is provided as well. The internal sample clock can be programmed via software for sample rates from 0.0625Hz to 50kHz.
