the maximum total length of the AS-Interface bus:
100 m (without repeater/extender).
–
the cable length of the load voltage connection
(depends on the current consumption of the valve
terminal and fluctuations in load voltage).

For connecting the valve terminal use the Festo cable
sockets type ASI-SD-FK... You will then comply with
protection class IP65. Proceed as follows:
1. Press the AS-Interface cable into the upper part of the
cable socket.
2. Make sure that the cable is free of tension.
3. Replace and screw tight the cable socket
(max. 0.3 Nm).
Seal open flat cable ends with the Festo cable cap type
ASI-KK-FK or the cable sleeve type ASI-KT-FK. In this way
you will avoid leakage currents and comply with protection
class IP65.
