Siemens SINUMERIK 828D

NOTICE
Protection against short circuit
A max. current of I
out
= 0.25 A at X111, X222, X333 where the demand factor is 100%: Pin 2
must not be exceeded.
Characteristics:
● No galvanic isolation.
● Protection against: Short-circuit, overtemperature, and loss of ground.
● Automatic disconnection in case of undervoltage.
