I/O configuration (hex)
ID code (hex)
Power supply
AS-Interface current input
Contact loading at SF1/2
Watchdog function (disconnects outputs in the event of AS-Interface fault)
Indication behavior
During operation, the LEDs on
the contactor indicate the
states shown on the right.

Input signals
AS-i +/AS-i –. Each of these terminals is jumpered and
connected twice to a 4-pole connector which is separate from
the other control inputs.
Advantages:
- The AS-Interface cable is not interrupted if the connector is
- The contactor remains functional through the local control
- Contactor ON/OFF
- Contactor ON/OFF
- Automatic/Local control:
- Remaining lifetime (RLT)
- Signal through free input, e.g. overload relay tripped.

Possibility of switching from automatic control to local control by
means of terminals H1/H2/H3, i.e. automatic control through
AS-Interface can be deactivated e.g. during startup or in the
event of a fault and the contactor can be controlled manually.
