I/O Expansion Board
Product Code: SEB-710
Key Features
– Extends the I/O capabilities of the SDC-650 and SDC-620 Controllers
– 8 relay outputs (either powered or potential free contacts)
– 8 Programmable digital inputs
– 8 Multi-purpose I/O points (either Inputs or Outputs)
– Complete intelligent offline operation
Installation
The SEB-710 offers a seamless integration with both the SDC-650 and SDC-620 Multiple Door Controllers, providing an expanded and flexible access control solution that can be tailored to meet the unique needs of your organization.
The board is easily mounted inside the enclosure of the SDC-650 or SDC-620 controller, fitting seamlessly below the main controller board. With the included stand-offs and nuts, installation is a breeze. The board connects to the controller through an expansion cable that is attached to the expansion headers on both boards.
Once connected, the main controller will detect the device and indicate this on its LCD display in the configuration section, ensuring a hassle-free setup process.
Operation
The SEB-710 IO Expansion Board operates by connecting to the expansion ports on the SDC-650 Multiple Door Controller or SDC-620 Ethernet Controller and expanding the input and output capabilities of the controller. Once connected and configured, the SEB-710 IO Expansion Board can receive inputs from external devices, such as doorc ontacts or motion sensors, and send outputs to devices such as locks or buzzers.
About the product
The SEB-710 IO Expansion Board is specifically designed to expand and enhance the Input and Output capabilities of the SDC-650 Multiple Door Controller and SDC-620 Wiegand Door Controller, providing a flexible and reliable solution for integrating additional devices into your existing access control system.
The board can be connected directly to the controller through its dedicated expansion ports and provides 8 relay outputs, 8 programmable digital inputs, and 8 multi-purpose I/O connection points. These additional I/O points can be configured according to your system requirements, allowing them to function as either 8 additional inputs or 8 additional outputs. This provides the flexibility to configure the system with either 16 outputs and 8 inputs or 8 outputs and 16 inputs, depending on the application and installation needs.
The SEB-710 supports potential-free contacts when the configurable I/O points are set as outputs, allowing the board to control higher-current devices such as magnetic locks, while also supporting low-current devices such as LEDs on mimic panels and other monitoring equipment through relay switching.
Designed for optimal performance, reliability, and a hassle-free installation process, the SEB-710 IO Expansion Board includes a separate 12Vdc power input connector for connecting an external power supply. This ensures that sufficient power is available for all connected output devices when required, helping maintain stable and dependable operation.
Additionally, the board features diagnostic LEDs positioned close to their relevant terminals, providing clear visual feedback and additional guidance during installation, configuration, and troubleshooting.
If you are looking to expand the functionality and capabilities of your access control system, the SEB-710 IO Expansion Board provides an ideal solution by offering increased flexibility, improved device integration, and enhanced system control.
Please note: The SEB-710 IO Expansion Board is not compatible with, and cannot be installed on, the SDC-320 Wiegand Controller.
