CONNECTION OF Q2000H & Q9000H TO DIFFERENT SIGNAL SOURCES

TTL or CMOS logic output
Set hysteresis to 100 mV
Adjust trigger level to:
1. 1 V for 5 V TTL logic
2.5 V for 5 V CMOS logic
4.0 V for 12, 15 or 24 V CMOS logic



3-wire active NPN open collector output
Set hysteresis to 100 mV
Adjust trigger level to -1 V



2-wire passive magnetic pickup
Set hysteresis to 10 mV for best low frequency response, to 100 mV for best noise rejection. Adjust trigger level to 0 V. A load resistor R may be required by the probe manufacturer.



3-wire PNP open collector output
Set hysteresis to 100 mV
Adjust trigger level to -1 V



2-wire NPN open collector output
Set hysteresis to 100 mV
Adjust trigger level to 2.5 V

3-wire active NPN open collector output (activated <1 mA, deactivated >3 mA)
Set hysteresis to 100 mV
Adjust trigger level to 1.5 V
