• Analog Input Channels 31 to 48:
• One 24-bit, Delta-Sigma A/D converter per channel for simultaneous, high-resolution
• 30 VAC, 60 VDC continuous functional isolation ch-ch and ch-gnd, verified by a 500 Vpk
• Throughput rate of up to 10 Samples/s for all channels
• Software or external, digital trigger on digital input line 0 starts acquisition
• Auto-calibrating front-end resets the zero point on each power-up; in addition, the
• Measurement Calibration Utility allows you to calibrate the instrument in the field (see
• 8 opto-isolated digital input lines; you can read the digital input port through the analog
• 8 opto-isolated digital output lines; the outputs are solid-state relays that operate from

4-wire, 3-wire, or 2-wire configurations; the DT9872 automatically linearizes the
measurements and returns the data as 32-bit, floating-point temperature, resistance, or
voltage values
Input range of ±1.25 V
Direct connection of analog input channels for differential voltage inputs; removable
screw terminal blocks for each channel for quick wiring
Software-selectable input range of ±10 V or ±60 V (note that for the ±60 V range, no
more than 30 Vrms, 42.4 Vpk, 60 VDC is allowed)
