CONNECTIONS & CONFIGURATION SWITCH SET-UPS FOR VARIOUS SENSOR OUTPUTS
NOTES:
1.
SENSOR SUPPLY VOLTAGE AND CURRENT
The +12 V sensor supply voltage on the “DC OUT” Terminal is nominal with
±25% variation due to line and internal load variations. All RLC sensors will
accomodate this variation.
2.
HI/LO FRQ. SELECTION
The “HI/LO FRQ.” Selection switch must be set on “LO FRQ.” when switch
contacts are used to generate count input signals. Since the “LO FRQ.” mode
also provides very high immunity against electrical noise pickup, it is
recommended that this mode also be used, whenever possible, with
electronic sensor outputs, as added insurance. The “LO FRQ.” mode can be
used with any type of sensor output, provided count pulse widths never
decrease below 5 milliseconds, and the count rate does not exceed 100 cps.
3. V
IL
and V
IH
levels given are nominal values ±10% when counter voltage on
“DC OUT” Terminal is +12 VDC. These nominal values will vary in
proportion to the variations in “DC OUT” Terminal voltage, caused by line
voltage and load changes.
4. When shielded cable is used, the shield should be connected to “COMM.” at
the counter and left unconnected at sensor end.
