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.
