Note
Do not wire vacant pins.
Note
Apply a voltage between 4VDC and 27VDC on the equipment side. Do not apply 5VDC
power on the equipment side. The output signals are generated from an open collector and
the pump provides 5VDC power for input signals.
Note
Wire all signals with the correct polarity (SIG./COM.).
Note
When output signals energize an inductive load such as a relay, insert a diode (100V. 1A
class) to limit the back electromotive force during de-energization.
