AMC2 - Input/Output Extension Boards
The AMC2 16I-16O-EXT, the AMC2 16I-EXT and/or the
AMC2 8I‑8O-EXT extension boards can only be used
with the AMC2 access controller and provides
additional input and output contacts.
The AMC2 controller has eight input and eight output
signals. The AMC2 determines the door status (open
or closed) via the analog input signals. The relay
outputs can be used to activate locking mechanisms,
If there are not enough contacts available on the AMC2
to transfer the necessary signals, up to three AMC2 xI-
xO-EXT units can be connected to provide additional
inputs and outputs.
Systems with Access Personal Edition Software
can only connect one I/O-Extension to an AMC2
The electronics are located in a plastic housing, similar
to the one on the AMC2 controller.
The AMC2 16I-16O-EXT has 16 analog inputs and 16
relay outputs. It receives door status signals via the
inputs and can authorize door releases or send
messages to external surveillance systems via the
RS485 connection to the AMC2 controller
Three models available one with 8 inputs & 8
outputs, one with 16 inputs & 16 outputs, and one
with 16 inputs
Status of inputs and outputs shows on AMC2 LCD
Transfer rate to EXT interface (RS485): 9,6 kBit/sec
The AMC2 Extensionboards can be supplied with
the PBC-60 power supply unit with integrated UPS.
Reduced versions of the extension board are also
obtainable to make full use of the available signals.
The AMC2 8I-8O-EXT module has eight input and eight
output signals. The AMC2 16I-EXT has 16 analog
The AMC2 xxx-EXT is integrated into the system via the
