Connecting analog input devices

The AMC2 has 4 analog inputs, for example, for potential-free lock mechanisms, or to detect
whether a lock is closed or open. The inputs will be connected to the 2-pin pluggable screw
connectors: S3, S4, S8 and S9 - refer to Connecting diagrams, page 45 .
Notice!
Risk of damage to equipment
i
Do not connect external power supply to the AMC2 inputs.
When connecting a relay output to an AMC2 input use dry mode with potential-free contact -
refer to Connecting relay outputs, page 27 .

The AMC2 can also detect the wiring conditions 'short circuit' and 'broken', and hence trigger
an alarm if the appropriate devices are connected.

The resistor values can vary and depend on the used lock system.
