Connecting to the input terminal
For the Non-voltage contact input to be connected to the Actual input, use the circuit with less
chattering which can steadily turn on/off the voltage/current of 5V/15mA.
Keep a time interval of 50mSec or more between input signals. Also for the time interval
between the time when input signal is turned off until the time when next signal is
turned on, keep 50mSec or more.
For the input signal, be sure to connect the non-voltage contact signal.

Examples of connection (Output side)
Contact output
(
LED lights up with ON
)
Use it within the driving current per terminal. If the specified power voltage or driving current
are exceeded, connect the drive circuit like relay during use.
Or, if inductive load such as lamp or relay is connected, take necessary actions for inrush
current.
