Revision as of 21:18, 22 June 2005
revisions from POT4a
- changed reference from TL1431 to fixed voltage MAX1631
- added circuit to make REF- and REF+ approximately symmetrical about COM
- OPAMP drives REF- and REF+ is a precise voltage above REF-
Power Supply
- +12V, GND, -12V recommend
- Supply current < 50mA (20mA typical)
- Maximum supply voltage is +-15V
Identification
- POT4b is a green PCB with white silk screen on two sides.
- Dimensions 1.75" x 0.85"
- Two mounting holes (diameter = 0.125"), top side clearance > 0.25"
- The color of DL1,DL2 indicates the input configuration 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.
- DK1 : The intensity of this dual RED/GREEN LED indicates the voltage of the "position signal".
