Header Pinouts : POT4 POT4a POT4b
Contents
Input header (5 pin)
Connection for a potentiometer
- REF+ : Positive reference output
- SIG : Potentiometer wiper "position" signal
- REG- : Negative reference output
- SHLD : Connect to the shield that encloses lead wires and potentiometer. Do not connect to the chassis or "GND"
- PKUP : Not used (Negative amp input)
Connection for a strain gauge bridge
- REF+ : Positive reference output, connect to "top" of bridge
- SIG+ : Amplifier positive input, connect to bridge signal (+)
- REG- : Negative reference output, connect to "bottom" of bridge
- SHLD : Connect to the shield that encloses lead wires and bridge. Do not connect to the chassis or "GND"
- SIG- : Amplifier negative input, connect to bridge signal (-)
"POS-PWR" Power input / "Position" output header (5 pin)
- +12 : Connect to a low noise +12V power supply
- P+ : Positive going differential "Position" output
- GND : Connect to
- P- : Negative going differential "Position" output
- -12 : Connect to a low noise -12V power supply
NOTES:
- P+ and P- are connected to low impedance drive though a 50 ohm resistor
- Capacitance of 1.1uF (typical) is placed across P+ / P- which forms 1st order lowpass filter with Fc=1.45KHz
- P+ and P- are fully differential and are NOT ground referenced. For single ended operation, at the receiving end, connect P- to the local ground.
"Velocity" differentiated output header (2 pin)
- V+ : Positive going "Velocity" output
- v- : Negative going "Velocity" output
NOTES: See preceding notes for P+/P- as V+/V- are also differential outputs
