The device is equipped with a supervised buffered power supply and a set of IO lines, including 2 relay outputs. Two Wiegand readers or two PRT series readers (RACS CLK/DTA interface) can be connected to the expander; however, for PRT readers, the internal firmware must be uploaded. MCX402-BRD provides a 0.2 A supply output for the readers and a 1.0 A supply output for door equipment (lock, siren, etc.). The expander is supplied from an 18 V/40 VA transformer and connected to the access controller through RS485 lines. Any type of signal wire can be used for RS485 lines and laid down using free cable topology. Optionally, the expander can be supplied from an 18 V/50 VA transformer and supported by the PS1A-LCK power supply module. In such a case the entire system offers 2 x 1.0 A and 2 x 0.2 A supply outputs. MCX402-BRD is offered as an electronic module dedicated to installation on DIN rail. --- ### Features - 2 door expander for RACS 5 system - supports 2 Wiegand readers (26-66bit) - supports 2 PRT series readers (RACS CLK/DTA) - 8 inputs NO/NC - relay output 30 V/1.5 A - relay output 30 V/5.0 A - 2 transistor outputs 15 VDC/1.0 A - supply output 12 VDC/1.0 A - supply output 12 VDC/0.2 A - supplied from 18 VAC/12 VDC/24 VDC - built-in supervised 1.5 A power supply - supports 7 Ah battery - RS485 free topology - CE mark --- ### Versions **MCX402-BRD** 1 door expander; battery charge and maintenance; 1.2 A power supply output; 18 VAC/40 VA power supply; Wiegand interface for 2 readers --- [WHERE TO BUY](https://www.roger.pl/index.php?option=com_storelocator&view=map&Itemid=525&lang=en) --- ### Download [ pdfMCX402-BRD Installation Manual(488 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=3246-mcx402-brd-installation-manual&category_slug=manuals&Itemid=642&lang=en) [ pdfMCX402-BRD Operating Manual(986 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=2624-mcx402-brd-operating-manual&category_slug=manuals&Itemid=642&lang=en) [ pdfMCX402-BRD Data Sheet(224 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=2610-mcx402-brd-data-sheet&category_slug=data-sheets&Itemid=646&lang=en) [ pdfMCX402 Declaration of Conformity EC(129 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=2126-mcx402-declaration-of-conformity-ec&category_slug=certificates&Itemid=649&lang=en) [ ArchiveMCX402-BRD Firmware v1.2.0.310(134 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=4000-mcx402-brd-firmware-v1-2-0-310-1&category_slug=firmware&Itemid=651&lang=en) --- ### Related products [ ![](https://www.roger.pl/templates/yootheme/cache/61/mc16-intro-614f01ac.png) ### Access Controllers of the RACS 5 System → ](https://www.roger.pl/index.php?option=com_content&view=article&id=696:access-controllers&catid=104&lang=en-GB) [ ![](https://www.roger.pl/templates/yootheme/cache/eb/mct82m-intro-ebb1e754.png) ### Proximity Readers of the RACS 5 System → ](https://www.roger.pl/index.php?option=com_content&view=article&id=695:proximity-readers&catid=104&lang=en-GB) [ ![](https://www.roger.pl/templates/yootheme/cache/b5/mct12-intro-b538d83a.png) ### PRT Series Proximity Readers → ](https://www.roger.pl/index.php?option=com_content&view=article&id=493:proximity-readers&catid=121&lang=en-GB) [ ![](https://www.roger.pl/templates/yootheme/cache/42/ps1a-lck-intro-425c5f8f.png) ### PS1A-LCK Supply Module → ](https://www.roger.pl/index.php?option=com_content&view=article&id=423:ps1a-lck-supply-module&catid=110&lang=en-GB) [ ![](https://www.roger.pl/templates/yootheme/cache/b5/roger-vdm-intro-b5beda13.png) ### RogerVDM Windows Application for RACS 5 Device Setup and Maintenance → ](https://www.roger.pl/index.php?option=com_content&view=article&id=378:rogervdm-windows-application-for-racs-5-device-setup-and-maintenance&catid=105&lang=en-GB) --- ### Quick links [ ![](https://www.roger.pl/images/ikony-oferta/wsparcie%201.svg)### Inquiry Więcej ](mailto:support@roger.pl) [ ![](https://www.roger.pl/images/ikony-oferta/gdzie-kupic.svg)### WHERE TO BUY Więcej ](https://www.roger.pl/index.php?Itemid=525) [ ![](https://www.roger.pl/images/ikony-oferta/cennik.svg)### Download Więcej ](https://www.roger.pl/index.php?Itemid=544) [ ![](https://www.roger.pl/images/ikony-oferta/kontakt.svg)### Contact us Więcej ](https://www.roger.pl/index.php?Itemid=523)
