Wiegand interface for card readers

The AMC2 provides two ports for connecting a maximum of 2 readers with Wiegand
interfaces. Each interface is connected using a 10-pin pluggable screw - refer to Connecting
diagrams.
Figure 4.16: Location of the Wiegand interface (port) for readers
These interfaces are point-to-point connections, and each can support only a single reader
with a maximum cable length of 90 m (300 ft) for 24 AWG or 150 m (500 ft) for 22 AWG.
Readers are addressed according to their respective interface numbers.
Notice!
When wiring the readers, the voltage loss on the line must be taken into account. The voltage
i
must be maintained according to the specifications of the reader.
If this is not the case, use a cable with a larger cross-section or a separate power supply with
the reader.

Connecting relay outputs

To operate locks or alarm systems, the AMC2 has four relay outputs. The outputs will be
connected to the 3-pin pluggable screw connectors S5, S6, S10 and S11- refer to chapter
Connecting diagrams, page 45 .
Figure 4.17: Location of the relay output connectors
By default, the relay outputs are connected as floating contacts (E1). However, it is possible
to connect the internal voltage 12/24 V of the AMC2 to each relay output (E2) to control
external consumers.
