Design and application 

MCX4D is I/O expander dedicated to control four doors with MCT readers (RS485) in RACS 5 system. 
Additionally the expander operates as distributor of 12VDC power supply and RS485 bus. For each door the 
MCX4D offers two inputs, two outputs, RS485 interface, 1.0A main power supply and 0.2A auxiliary power 
supply. All outputs of the expander are protected against overload. The MCX4D is supplied from the same 
13.8VDC PSU as access controller, 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, 0.6A or 0.9A current. The expander is equipped with removable terminal blocks which 
facilitate electrical connections during installation and maintenance. MCX4D can be also used with PRT and 
Wiegand readers and then such readers must be connected to the controller directly or through dedicated 
expanders (e.g. MCX402DR, MCX102DR, MCX16-NT). Inputs and outputs of the expander can be 
configured to any functions and used for purposes not related to door control. MCX4D is offered individually 
as electronic module or as a component of MC16-PAC-3-KIT and MC16-PAC-4-KIT.
