Key Specifications

MB1S (MB1SA2V)

Direct Full Scale Analog Input Range: +/- 2.00000V DC

Input Impedance: 1GΩ min, 100GΩ typical.

Optional on-board input resistor divider network for wide input voltage ranges

Resolution: +/- 1 digit, (+/-10µV) @ Vin = 1.00000V (16x input averaging)

Overvoltage Protection: 20V DC

Conversion Sample Rate: 3-samples/sec (from 1 sample/min. to 10 samples/sec.)

No external power source necessary, draws power directly from the PC printer port

Applications

Applications for the MB1S Board include embedded digital panel meters, customized

instrumentation displays, temperature monitoring, high resolution DVM’s, weigh scales, signal

conditioners, laboratory data-logging, process monitors, portable/field troubleshooting and calibration.

Configuration & Outline Drawing

MB1S boards include a DB25 pin connector that plugs directly into the parallel printer port of a

desktop or laptop PC computer for operation, initial setup & calibration. The board outputs 24 bit serial

data (23-bit serial data plus sign bit) to the PC or other digital processors for further data processing.
