OUT3 has different electrical features, since it is a bi-directional solid state relay with a
built-in current limit protection. If this output is continuously driven, the maximum current
must be not more than 200 mA although more than 300 mA may be reached in pulse
conditions for an ambient temperature of 25°C. At the maximum ambient temperature of
50°C the maximum respective current is 160 mA continuous and 240 mA pulse.
The OUT3 electrical features are given below:

The command signal is filtered and generates a delay of about 50 µs for OUT1 and OUT2
and 1 ms for OUT3.
When the load is powered by an external power supply, the voltage must be less than 30 V.
