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).
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.
