0-10V Interface Option Board
SECTION 9
The 0-10 V interface board is available as an option for the Model 2002. This board provides
dual voltage channels linearly proportional to the HPM 2002’s pressure reading. Please note that
use of the Model 2002 with this option requires a CPU with firmware version 1.6 or later for
proper operation.

9 Channel 2 Shield/Analog Common
Both output channels are true differential and are short circuit protected with 100 Ω output
impedence. While this allows either side of the output channel to be grounded, best results will be
obtained by using a differential input measurement system. The output can be modified for
single ended use, if necessary contact the factory for details.
