3.5 Connect the AS−Interface bus and the load voltage
The sensor supply for the inputs is provided via the
AS−Interface bus.
Warning
Use only power units which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN
EN 60204−1. Observe also the general requirements for
PELV power circuits as per IEC/DIN EN 60204−1.
Note
The valves (outputs) are always supplied with 24 V
additional supply, separate via the load voltage
connection.
Please note with branch lines:
the maximum total length of the AS−Interface bus
(100 m without repeaters/extenders)
the length of the load voltage connection cable
(depends on the current consumption of the valve
terminal and fluctuations in load voltage).
