• Use in sinking mode
The external power supply changes the voltage level of the pulse train output signal. Keep the voltage from an
external source between 10.8 Vdc to 16.5 Vdc. Adjust the load impedance to keep the current at 16 mA or
lower.

(Default)
H3-09 = 2: 4 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
H3-09 = 3: 0 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
Voltage input V
H3-09 = 0: 0 V to 10 V/0% to 100% (with zero limit) (input impedance: 20 kΩ)
H3-09 = 1: 0 V to 10 V/0% to 100% (without zero limit) (input impedance: 20 kΩ)
Note:
Use tweezers or a jig with a tip width of approximately 0.8 mm (0.03 in) to set DIP switches.
