The expander provides two parametric input lines and two relay outputs. Each of the inputs can be individually parameterized in terms of the reaction time and topology of the attached contacts and resistors. Optionally, the inputs can be configured for double wiring mode, which enables the connection of two independent NO or NC contacts to each of the inputs and thus doubling the number of input signals monitored by the expander. Each of the relay outputs provides a normally open and normally closed contact and can be switched off in the idle state (the so-called normal polarity) or on (the so-called reverse polarity). Communication with the controller takes place via the modified RS485 standard, which allows for the creation of star and tree cabling structures. The communication bus to which the expander is connected may be up to 1,200 m long and be made using any type of signal cable. Device configuration and firmware update are performed via the RS485 interface and RogerVDM software (Windows). --- ### Features - 2 parametric inputs - 2 relay outputs - configuration of input reaction time - double Wiring input option - output activation signalled by LED indicator - onfiguration of output default state (polarization) - configuration and firmware update through RS485 - 12 VDC power supply - CE mark --- ### Versions **MCX2-BRD** I/O expander; 2 supervised inputs, 2 relay outputs 1.5 A/30 V; 13.8 VDC supply input --- [WHERE TO BUY](https://www.roger.pl/index.php?option=com_storelocator&view=map&Itemid=525&lang=en) --- ### Download [ pdfMCX2-BRD/MCX8-BRD Installation Guide(483 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=2353-mcx2-brd-mcx8-brd-installation-guide&category_slug=manuals&Itemid=642&lang=en) [ pdfMCX2-BRD/MCX8-BRD Operating Manual(1.04 MB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=3195-mcx2-brd-mcx8-brd-operating-manual&category_slug=manuals&Itemid=642&lang=en) [ pdfMCX2 Declaration of Conformity EC(129 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=2117-mcx2-declaration-of-conformity-ec&category_slug=certificates&Itemid=649&lang=en) [ ArchiveMCX2-BRD Firmware v2.0.30.266(35 KB)](https://www.roger.pl/index.php?option=com_docman&view=document&alias=3329-mcx2-brd-firmware-v2-0-30-266-1&category_slug=firmware&Itemid=651&lang=en) --- ### Related products [ ![](https://www.roger.pl/templates/yootheme/cache/61/mc16-intro-614f01ac.png) ### MC16-BAC Building Automation Controller → ](https://www.roger.pl/index.php?option=com_content&view=article&id=391:mc16-bac-building-automation-controller&catid=107&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/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) [ ![](https://www.roger.pl/templates/yootheme/cache/21/rud-1-intro-21ff8f2e.png) ### RUD-1 Interface RS485 to USB → ](https://www.roger.pl/index.php?option=com_content&view=article&id=555:rud-1-interface-rs485-to-usb&catid=142&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) ## Schema ```json { "@context": "https://schema.org", "@type": "BreadcrumbList", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Start", "item": "https://www.roger.pl/en" }, { "@type": "ListItem", "position": 2, "name": "Products", "item": "https://www.roger.pl/en/products" }, { "@type": "ListItem", "position": 3, "name": "RACS 5 Access Control System", "item": "https://www.roger.pl/en/products/racs-5-access-control-system" }, { "@type": "ListItem", "position": 4, "name": "Expanders", "item": "https://www.roger.pl/en/products/racs-5-access-control-system/expanders" }, { "@type": "ListItem", "position": 5, "name": "MCX2-BRD | I/O Expander", "item": "https://www.roger.pl/en/products/racs-5-access-control-system/expanders/mcx2-brd-i-o-expander" } ] } ``` ```json { "@context": "https://schema.org", "@type": "Product", "name": "MCX2-BRD | I/O Expander", "image": "https://www.roger.pl/", "description": "MCX2-BRD is an input and output expander designed to work in the RACS 5 access control system." } ```
