Bosch AMC2-4W, Installation Manual

Page: 44 / 70

Connecting Analog Input Devices
The AMC2-4W 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 60.
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 39.

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