DescriptionThe OM-USB-1208HS, OM-USB-1208HS-2AO and OM-USB-1208HS-4AO are USB 2.0 full-speed voltage input data acquisition modules (fully compatible with both USB 1.1 and USB 2.0 ports). These are stand-alone plug-and-play modules which draw power from the USB cable– no external power supply is required. All configurable options (including individual channel ranges) are software programmable, and the modules are fully software calibrated. All three OM-USB-1208HS modules provide 13-bit resolution, and 4 differential or 8 single-ended analog inputs. These modules support software programmable ranges from ±5 to ±20V in a differential configuration, and ±2.5 to ±10V, and 0 to 10V in a single-ended configuration. In software-paced mode, these modules can sample at a maximum of 4 kS/s. In hardwarepaced mode, they can sample at a maximum of 1 MS/s. The OM-USB-1208HS-2AO provides two 12-bit analog outputs, and the USB-1208HS-4AO provides four 12-bit analog outputs.
