A link with exact information on what this is used for and how it used can be found here: ftp://ftp.pasco.com/manuals/English/CI/CI-7500/012-06772C/012-06772C.pdf • 12 VDC to 20 VDC at 2 A, 2.1 mm jack • SCSI, 8-bit data width and a MDB50 female connector • Internal active termination provided Alternate computer connection: • Serial RS-232 with an 8-pin MDIN female connector • 19.2K bits/s, 1 start bit, 8 data bits, 1 stop bit • 4 identical digital input/output channels • TTL compatible input/output levels with 8 mA maximum drive current • Maximum input logic transition time: 500 ns • Electrostatic Discharge (ESD) protected inputs assuming the human body model standard, Mil-Std-3015.7 • Edge sensitive and sampled at 10 KHz (100 µs). (1 µs resolution for the Motion Sensor) • 3 identical channels with differential inputs and 1 M ohm impedance • +/-10 V maximum usable input voltage range (+/-12 V absolute input voltage range) • ESD protected input similar to that of the digital channels • 3 voltage gain settings on each analog channel: 1, 10, and 100 • Small signal bandwidth up to the ADC: 1 MHz for a gain of 1, 800 KHz for a gain of 10, and 120 KHz for a gain of 100; input amplifier slew rate: 1.2 V/ µs (The actual bandwidth is determined by the sampling rate of the ADC.) • 5 input sources for the 12-bit ADC: channels A–C and analog output voltage and current. • Voltage resolution at the ADC input: 4.88 mV (.488 mV at a gain of 10; 0.049 mV at a gain of 100) • Current measurement resolution: 244 µA, where each volt measured represents 50 mA • Offset voltage accuracy < +/-3 mV. (For measuring full-scale voltages (or 1 V with a gain of 10, etc.) the total error will be less than +/-15 mV, accounting for the gain error in the input amplifier.) • Sample rate range: once every 3600 seconds – 250 KHz (The conversion time between consecutive channels in a burst is 2.9 µs.) • 8X oversampling for improved accuracy for sample rates < 100 Hz. • DC value ranges: -4.9976 V to +5.0000 V in steps of 2.44 mV • Accuracy at the DIN connector: (+/-3.6 mV +/-0.1% full scale) • Peak-to peak amplitude adjustment ranges for AC waveform: 0 V to +/-5 V in steps of 2.44 mV • AC waveform frequency ranges: 1 mHz (0.001 Hz)–50 KHz, +/-0.01% • Maximum amplified output at the banana jacks: about 300 mA at +/-5 V, current limited at 300 mA +/-12 mA Pasco supports this unit, and software along with sensors are readily available and inexpensive. This would be a great add on unit or a new one for anybody having a need in a scientific setting or teaching setting. The unit is cosmetically very nice, and works properly. This item was acquired through liquidation from a working environment with hardly any reported use. As a sensitive electronic item, It is guaranteed against NO DOA ONLY. There is no other warranty expressed or implied as I do not have the equipment to fully test this item. Click here to check out my~~~~> other items! Click here to add me to your~~~~> favorites list!
