Connecting Analog Input Devices

The AMC2-4R4 has 8 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 - refer to Connecting Diagrams, page
44.
Notice!
Risk of damage to equipment
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 30.

The AMC2-4R4 can also detect the wiring conditions 'short circuit' and 'broken', and hence
trigger an alarm if the appropriate devices are connected.
