• TTL inputs: An external 5 VDC power supply and 10 k Ω pull-up
resistor is recommended.
• CMOS inputs: An external 3 to 15 VDC power supply and 10 k Ω
pull-up resistor is recommended.
• 12 VDC Open-collector inputs: An external 12 VDC power
supply and 10 k Ω pull-up resistor is recommended.
• 24 VDC Open-collector inputs: An external 24 VDC power
supply and 10 k Ω pull-up resistor is recommended.

3. Sensor Pulse Output Connections (sec. 8.1)
3.1 Signet instrument with internal open-collector excitation
voltage and pull-up resistor.
Technical Notes:
• Use 2-conductor shielded twisted-pair cable for output lines up
to 30 m (100 ft.) max.
• Pull-up resistor NOT REQUIRED when connected to
Signet instruments.

4. Auxiliary Pulse Output Connections
4.1 Pulse mode (sec. 8.2) - External device control
• The auxiliary output can be con fi gured for either TTL, CMOS,
or open-collector compatible inputs using the proper pull-up
resistor and an external power supply.
Technical Notes:
• Open-collector transistor, optically isolated, 5 mA max. sink,
28 VDC max. pull-up voltage.
• Programmable pulse width, 0.10 - 999. seconds (sec. 9.2 M)
• Selectable Active high or active low pulse logic (sec. 9.3 J).
• Use 2-conductor shielded twisted pair cable for AUX output lines
to 30 m (100 ft) max.
