Hi, Does anyone know what the input voltage specification for ON or Off (Synch switch) for the Queue track card. What is the min voltage level to be classified as ON.

Check the conveyor tracking application manual [3HAC16587-1\_revH]. I says:

Technical specification for encoder interface  
DSQC 377B

Power supply: 24 VDC, typically 50 mA, maximum 200 mA  
Operating temperature: +5A?C - +60A?C  
Encoder frequency: 0 - 20 kHz  
Encoder input current: 6.8 mA at 24 VDC\*  
Digital input current: 6.8 mA at 24 VDC\*

\*) 18 VDC \< ?\_~1?_T \< 35 VDC  
-35 VDC \< ?_~0?\_T \< 2 VDC
