USB-200 Series - 1

MEASUREMENT COMPUTING. 12-Bit Multifunction DAQ Devices Overview The USB-200 Series provides improved cost/performance compared to our similarly priced 12-bit DAQ devices. Each device provides eight single-ended (SE) analog inputs, eight DIO channels, one event counter, and external pacer I/O. The USB-202 and USB-205 also provide two analog output channels. Features • Eight 12-bit analog inputs • Sample rates up to 500 kS/s • Up to two analog outputs • Eight digital I/O lines • One 32-bit event counter input • External pacer I/O • No external power required • Available with enclosure and screw terminals or as board-only OEM with header connectors • ACC-205 DIN-rail kit available Supported Operating Systems • Windows® 10/8/7/Vista®XP 32/64-bit • Android™ Analog Input USB-200 Series devices provide eight 12-bit SE analog inputs. The analog input range is fixed at ±10 V. Sample Rate The maximum continuous scan rate is an aggregate rate. The following table lists the maximum rate per channel when scanning from one to eight channels. Analog Output (USB-202 and USB-205) The USB-202 and USB-205 standard and OEM versions have two 12-bit analog output channels. Both outputs can be updated simultaneously at a rate up to 125 S/s per channel. One output can be updated at a rate up to 250 S/s. The output range is fixed at 0 V to 5 V. External Pacer I/O Each USB-200 Series device provides one external clock input and one clock output for the analog input pacer. You can connect an external clock signal to the external clock input terminal. When using the internal clock, each device outputs the ADC sample clock. * Sample rates apply to standard and OEM versions USB-200 Series Selection Chart Measurement Computing
