Introduction
EXP2D/4D is I/O expander dedicated to control two doors with AC-MAX readers (RS485) in AC-MAX
system. Additionally the expander operates as distributor of 12Vdc power supply and RS485 bus. For each
door the EXP2D/4D offers two/four inputs, two/four outputs, RS485 interface, 1.0A main power supply and
0.2A auxiliary power supply. All outputs of the expander are protected against overload. The EXP2D/4D is
supplied from the same 13.8Vdc PSU as access central, readers and other door related devices and it
offers 1.2A current per door. The expander operates with backup battery which depending on particular
requirements can be charged with 0.3A or 0.6A current. The expander is equipped with removable terminal
blocks which facilitate electrical connections during installation and maintenance. EXP2D/4D can be also
used with Wiegand readers and then such readers must be connected to the central directly terminals D0
and D1 to inputs INn, INn+1. Inputs and outputs of the expander can be configured to any functions and
used for purposes not related to door control. EXP2D/4D is offered individually as electronic module or as a
component of AC-MAX-CU-2/4-KIT which additionally includes AC-MAX-CU-2/4 access central, PWR2D/4
power supply unit and BOX-IP-15/16 metal enclosure.
