Connecting analog input devices

The AMC2 has eight 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, S9, S15, S16, S20 and S21.
For more information on these connections, refer to Connecting diagrams, page 45 .
Notice!
Risk of damage to equipment
i
Do not connect external power supply to the AMC2 inputs.
When you connect an AMC2 relay output to an input, use the relay output in floating mode -
refer to Connecting relay outputs, page 29 .

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