Analog Input

The VSBC-8 employ a multi-range, 12-bit A/D converter which will accept up to eight single-
ended input signals. The converter features fast 6 microsecond conversion time, with channel
independent input ranges of 0 to +5V, ±5V, 0 to +10V, and ±10V.

Note!

Connector J10 also includes signals for the Opto 22 interface.

Warning!

All analog inputs are fault protected to ±16V (board power on or off). Exceeding
these maximums can cause permanent damage to the A/D converter circuitry.
Such damage is not covered under warranty.

C

ALIBRATION

There are no calibration adjustments. Calibration, if desired, is accomplished by mathematical
transformation in software.
