Technical Data
AS-Interface profile:
S-7.A.*.E
(S-7.F.F.F as option)
Extended
address range:
is supported
Serial
communication mode:
no
Inverse-polarity protection:
exists
Indication "Power":
LED3 (green)
Indication "Fault":
LED3 (red)
AS-Interface
Voltage range:
26,5...31,6 V
Max. power input:
<= 150 mA
Input delay time:
< 1 s
AS-Interface specification:
V3.0
Supply of
solenoid valves:
pwm-signals from
electronic module
Short-circuit protection:
yes
Excess voltage protection:
100mA
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 Profil S-7.A.*.Eonly).
Simultaneously LED3 flashes according to AS-Interface
specification alternately red/green.
Supply of sensors:
5 VDC (+/-5%)
Note:
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
