Contents
Power Supply
- +12V, GND, -12V required.
- Supply current < 50mA
- Maximum supply voltage is +-15V
Identication
- POT4 is a green PCB with white silk screen.
- Dimenstions 1.75" x 0.85"
- Two mounting holes (diameter = 0.125"), top side clearance > 0.25"
- The color of DL1,DL2 indicates the input configeration of the board
Led Indicators
- (DL1, DL2) : A pair of single LEDs indicate the present of power. These LEDs are aligned with the power input to the boards.
- RED : configured for potentionment inputs (#1-2)
- GREEN : configured with bridge inputs (#3-8)
- DK1 : The intensity of this dual RED/GREEN LED indicates the voltage of the "postion signal".
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
