*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.
*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.
*1 Le rôle du fusible du module de sortie est d'éviter
d'endommager le câblage externe dans l'éventualité d'un
court-circuit de la sortie de module. Il ne peut donc assurer
la protection des dispositifs de sortie.
Si un dispositif de de sortie est endommagé en un mode
de défaillance autre qu'un court-circuit, il se peut que le
fusible ne saute pas.
*2 La diode lumineuse "ERR" s'allume aussi quand
l'alimentation externe est coupée.
*3 Installer des résistances pour limiter le courant
LED à l'extérieur du A1S42Y.
*4 La tension d'alimentation (12/24 V cc)
s'exerce en sens inverse de la LED.
Si la tension inverse de pointe est insuffisante, raccorder
des diodes de protection en série avec chacune des LED.
