– Response delay
8 digital inputs each as per
IEC 1131-2 type 2
24 V DC, PNP,
status display (LED)
ON:
11 ... 30 V
OFF: -30 ... 5 V
≥ AS-interface bus
voltage − 2.5 V
Typ. 3 ms (at 24 V)
Diagnosis (see section 2).
– AS-Interface voltage and address,
watchdog, I/O status
– Additional power supply not applied
or undervoltage

LED display, peripheral fault
1)
The device is intended for use in industrial environments. Measures
may need to be implemented in residential areas for interference
suppression.
2)
Factory setting, set to 0
H
by some programming devices ≤ Spec. 2.1
when addressing the slave!
3)
The inputs are resistant to short circuits. If a short circuit occurs,
the slave will be switched off. The AS-Interface master regards this
slave as missing. When the short circuit is eliminated, the slave
indicates immediately that it is capable of functioning.
