Type CPA...-ASI-8E8A-Z
Additional supply (load voltage)
– Rated value (protected against
incorrect polarity)
– Residual ripple
– Current consumption
Valves
(see Pneumatics manual P.BE-CPA-...)
– Current consumption for 8 valve
solenoid coils (at 24 V)
– Switching on
– after current reduction (stationary)
3)
Digital inputs
– Design
– Logic level
– Sensor supply (US+/Us−)
– Response delay
Diagnosis (see section 2).
– AS-Interface voltage and address,
watchdog, I/O status
– Additional power supply not applied
or undervoltage
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
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.
