*1 The fuse in the output module is provided to
prevent the external wiring from burning in
the event of a short circuit in the module's
output. Consequently, it may not be able to
protect output devices.
If an output device is damaged in a failure
mode other than a short circuit, the fuse
might not be blown.
*2 The "ERR." LED will alxo come ON when
the external power supply is cut.
Pin No.

*3 Mount the resistors to limit
LED current externally to the
A1S42Y.
*4 The power supply voltage (12/24VDC) is
applied in the LED's reverse direction.
If the peak inverse voltage is insufficient,
connect protective diodes in series with
each of the LEDs.
