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.
