2. CJ series High speed Counter Units Operation Manual for NJ series CPU Unit W492 1 11 1 Introduction Additional Information As a general guideline to satisfy the above timing specifications you must pay attention to the type of output driver of the encoder being used the length of the encoder cable and the fre quency of the count pulses generated For example if you use an Open Collector encoder e g E6B2 CWZ6C at 24 V with 10 m cable you can typically generate count pulses up to 20 kHz Therefore if you want to generate count pulses with higher frequencies you should use a differ ent type of encoder e g E6B2 CWZ1X with Line Driver output or a fast push pull 24 V encoder e g E6C2 CWZ5GH or reduce the length of the encoder cable 1 3 4 Output Specifications Item Specification Driver Type Open Collector NPN PNP selectable External Power Supply 12 to 24 VDC 10 2 to 26 4 V 30 mA max at 26 4 VDC for PNP output without load current Maximum Switching Capacity 46 mA at 10 2 V to 100 mA at 26 4 V 200 mA maximum common see picture below Minimum Switching Current 5 mA Output ON delay 100 us max Output OFF delay 100 us max Leakage Current 0 1 mA max Residual Voltage 1 5 V max Short Circuit Protection No EN Additional Information Every Digital Output has 2 Output drivers available NPN and PNP available as separate pins on the front connectors Every Output can be separately configured for NPN or
