Technical data / AS-interface
AS-interface-profile:
S-7.A.*.E
Extended address mode:
is supported
Serial communication mode:
no
Inverse-polarity protection:
exists
Indication "Power":
LED 3 (green)
Indication "Fault":
LED 4 (red)
AS-interface voltage range:
26.5…31.6 V
External voltage supply
PELV
24 VDC
max. current consumption:
100 mA
(in case of supply of actuators from auxiliary energy)
150 mA
(in case of supply of actuators from AS-interface)
Input delay time:
< 1 s
AS-interface specification:
V3.0
Supply of solenoid valves:
pwm signal from
electronic module
Short-circuit protection:
yes
Excess voltage protection:
100 mA
Induction protection:
yes
Status indication of outputs:
LED on board
Response time of watchdog:
--- (watchdog not activated)
Short-circuit or excess voltage of actuator supply or
cable break at valves is signalled to the master via the
peripheral failure bit (profile S-7.A.*.E only). Simultaneously,
LED 3/4 flashes according to AS-interface specification
alternately red/green.
Supply of sensors:
5 VDC, 4,75…5,25V (sum of
all currents < 40mA)
Caution!
The sensor inputs and the
peripheral supply must not
be connected with installation-
GND.
Connecting terminals:
conductor cross section
0.5 – 1,5 mm² (with conductor
sleeve) complying with
AWG 20-16
AS-interface communication / data: see 6.7.
