Power Supply
- +12V, GND, -12V required.
- Supply current < 50mA
- Maximum supply voltage is +-15V
Jumpers
- JF1 : 3 way jumper used to select souce that drives that "Position" output. The signal source may be one of the following:
- Insturmentation amplifier output
- 2nd order low pass filter output
- 4th order low pass filter output
- JC1 : selects the "Shield" header signal source and is specified at assembly time. Signal sources include "GND", "COM", or "REF-".
assembly variations
POT4 can be built for either potentiometer input or bridge input. There are also several optional circuit modules.
- boards #1, #2 : fully built with lowpass filters, differentiation is configured for potentiometer input
- boards #3, #4 : minimally built for strain gauge bridge input
- boards #5 - #8: built for strain gauge bridge input and are minimally built with 2nd order LP filter
