On the U3-HV, the first 4 flexible I\/O are replaced with dedicated high-voltage analog inputs. The first 8 flexible I\/O lines (FIO0-FIO7) appear on built-in screw terminals. The other 8 flexible I\/O lines (EIO0-EIO7) are available on the DB15 connector.\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e\u003cbr\u003e\u003cstrong\u003e\u003cfont size=\"4\"\u003eAnalog Inputs:\u003cbr\u003e\u003c\/font\u003e\u003c\/strong\u003e\u003cbr\u003eThe LabJack U3 has up to 16 analog inputs available on the flexible I\/O lines. Single-ended measurements can be taken of any line compared to ground, or differential measurements can be taken of any line to any other line. Analog input resolution is 12-bits. The range of single-ended low-voltage analog inputs on the U3-LV is typically 0-2.4 volts or 0-3.6 volts, and the range of differential analog inputs is typically ±2.4 volts (pseudobipolar only). For valid measurements, the voltage on every analog input pin, with respect to ground, must be within -0.3 to +3.6 volts. On the U3-HV, the first 4 flexible I\/O are replaced with dedicated high-voltage analog inputs. The input range of these channels is ±10 volts or -10\/+20 volts. The remaining 12 flexible I\/O are still available as described above, so the U3-HV has 4 high-voltage analog inputs and up to 12 low-voltage analog inputs. Command\/response (software timed) analog input reads typically take 0.6-4.0 ms depending on number of channels and communication configuration. Hardware timed input streaming has a maximum rate that varies with resolution from 2.5 ksamples\/s at 12-bits to 50 ksamples\/s at about 10-bits.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cfont size=\"4\"\u003eAnalog Outputs:\u003cbr\u003e\u003c\/font\u003e\u003c\/strong\u003e\u003cbr\u003eThe LabJack U3 has 2 analog outputs (DAC0 and DAC1) that are available on the screw terminals. Each analog output can be set to a voltage between 0 and 5 volts with 10-bits of resolution. The analog outputs are updated in command\/response mode, with a typical update time of 0.6-4.0 ms depending on communication configuration. The analog outputs have filters with a 3 dB cutoff around 16 Hz, limiting the frequency of output waveforms to less than that.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cfont size=\"4\"\u003eDigital I\/O:\u003cbr\u003e\u003c\/font\u003e\u003c\/strong\u003e\u003cbr\u003eThe LabJack U3 has up to 20 digital I\/O channels. 16 are available from the flexible I\/O lines, and 4 dedicated digital I\/O (CIO0-CIO3) are available on the DB15 connector. Each digital line can be individually configured as input, output-high, or output-low. The digital I\/O use 3.3 volt logic and are 5 volt tolerant. Command\/response (software timed) reads\/writes typically take 0.6-4.0 ms depending on communication configuration. The first 16 digital inputs can also be read in a hardware timed input stream where all 16 inputs count as a single stream channel.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cfont size=\"4\"\u003eTimers:\u003cbr\u003e\u003c\/font\u003e\u003c\/strong\u003e\u003cbr\u003eUp to 2 flexible I\/O lines can be configured as timers.
