Overview: OMB-DAQ-2408 Series features
The OMB-DAQ-2408, OMB-DAQ-2408-2AO includes the following devices:
OMB-DAQ-2408
OMB-DAQ-2408-2AO
These devices are USB 2.0 high-speed devices supported under popular Microsoft
®
Windows
®
operating
systems. The OMB-DAQ-2408 Series is compatible with both USB 1.1 and USB 2.0 ports, although the speed
of the module maybe limited when using USB 1.1 ports.
Each OMB-DAQ-2408 Series device provides the following features:
16 single-ended (SE) or eight differential (DIFF) 24-bit analog inputs with sampling rates up to 1 kS/s.
Each channel is software-configurable as SE or DIFF. For each DIFF channel pair, you lose one SE
channel.
Analog input ranges of ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, ±0.312 V, ±0.156 V, and ±0.078 V.
Up to eight analog inputs can be configured as DIFF thermocouple (TC) inputs, which include built-in
cold-junction compensation and open TC detection.
Computer protection provided through a minimum of 500 VDC input isolation between field wiring and the
USB interface.
Eight lines of digital I/O and two 32-bit counters.
Screw terminals for field wiring connections
The OMB-DAQ-2408-2AO also provides two 16-bit analog output channels. You can pace a single channel at
rates of up to 1 kS/s. You can pace both channels simultaneously at rates of up to 500 S/s.
