Figure6.9: Using supervised or isolated inputs of the CONTROL IN port
Supervised control inputs
The supervised control inputs can be used as
– normal logical (high/low) input (with low ≤ 5 V or high ≥ 10 V),
– analog input (0-24 V) or
– supervised input with states active, not active, open circuit or short circuit.
When using a supervised input (e.g. for connecting a CIE) add two resistors as illustrated
above (if not already included in the outputs of the connected device).
i
Notice!
The supervised inputs are internally equipped with 8.2kΩ pull up resistors. The ground pins
are equipped with a common self resettable 140mA fuse.
Isolated control inputs
The isolated control inputs can be used as normal logical (high/low) input (with low <= 5 V or
high >= 10 V) only. This inputs comply with VDE 0833-4.
