For the operating conditions of applied voltage (User Power) +12V, load resistance
10kΩ, and cable length 1m, the timing is shown in the table below.

Since it varies depending on the applied voltage, load resistance, cable length,
etc., check the actual environment before use.

Please note that the recommended load resistance of Opto output is 10 kΩ (rated 1/10
W) or more. The 270 Ω resistor shown in the circuit diagram is the MINIMUM resistance
that should be used. The response speed from On (High) to Off (Low) depends on the
voltage applied to Opto output and the value of the load resistance. Higher load
resistance results in slower response. If the response at 10 kΩ is slower than desired,
you can try reducing the load resistance in order to increase the response speed but DO
NOT go below the minimum 270 Ω value.
The load resistance loss can be calculated as follows.
load resistance loss ≒ (voltage applied to Opto output ) / (load resistance)
