Installing and Wiring the DSM314 84
Strobe Response: Minimum Pulse Width: 3 microseconds Position
Capture Accuracy: +/- 2 counts with an additional 10
microseconds of variance
Note: Use (+) Input for single ended mode and leave (-) input floating. Use faceplate 0v pins for
common mode reference or single ended signal return. Inputs can be driven by 5v TTL or CMOS
logic.
Single Ended 5v Sink Input
I/O Type: Single Ended 5v Sink Input
Circuit Type: Sink Input (4.7K ohm pull-up to internal +5v) Input
Impedance: 4.7K ohms to +5v
Maximum Input Voltage: +/- 10.0 v
Logic 0 Threshold: +0.8 v max
Logic 1 Threshold: +2.0 v min
Input Filtering: 1.0 microseconds (typical) hardware filter + position
loop sampling rate (0.5, 1.0 or 2.0 milliseconds).
Note: This input must be pulled to 0v to turn on.
Optically Isolated 24v Source / Sink Inputs
