Output terminal:
A terminal common to all outputs is used.
Use a smooth power supply of 5 to 24V DC for the external power supply for load driving.
Circuit insulation:
The circuit built in the PGU is isolated from the output transistor with a photo-coupler, however,
the transistor base current is supplied
by the built-in
24V DC power supply used for the
general-purpose inputs.
Operation lights:
The output LED indicator is arranged in the photo-coupler drive circuit.
The output transistor is turned ON when the LED is turned ON,
Response time:
The switching time from
ON
to
OFF
and OFF to ON is less than 1 msec.
Output current:
It is possible to flow a max. of 0.3A current per 1 output point.
