One per channelInput format: Differential (may be used as single ended by grounding one input, 0-25ma)Input scaling: Ten (10) unipolar channels, 0-25ma Full Scale (FS)This module will not sense open InputsInput voltage: Not to exceed 3 voltsInput impedance: 100 min.Accuracy: 0.1 % FS range over temperature. (no missing codes to 16 bits)Linearity error: 8 LSB’s max. over temperatureSampling rate: 200 KHz max per channel, programmableData buffering/triggering: See Operations Manual for detailsBandwidth: 20 KHz per channelGroup delay: 30 s (Time for data sample to propagate to data register)Programmable filter: Each channel incorporates a fixed second order anti-aliasing filterand a post filter that has a digitally adjustable break point(programmable from 10 Hz to 10 KHz in 10 Hz steps).Common mode rejection: 70 dB min. at 60 Hz. Roll off to 50 dB min. at 10 KHz.Common mode voltage: Signal voltage plus Common mode voltage is 80 volts.Note: A/D differential inputs must not “float”.Input source must have return path to ground.Output logic: Unipolar output range from 0 to FFFF full scaleESD protection: Designed to meet the testing requirements of IEC 801-2 Level 2.(4KV transient with a peak current of 7.5A and TC of approximately 60 ns)Power: +5 VDC @ 500mA typical, 750mA max.Ground: Channel inputs are differential, but referenced to system ground.Weight: 1 oz.
