Remote I/O Expansion Board
Product Code: SEB-722
Key Features
– Extends the capabilities of the SDC-650 and the SDC-620 Controllers
– 2 Relay Outputs (powered or potential-free)
– 4 Programmable digital inputs
– 2 Wiegand reader inputs
– RS-485 connection for up to 4 x SSR-201 Proximity Readers
– In-circuit programming for easy product updates
– Rotary coded address switch for easy addressing
Installation
The SEB-722 is thoughtfully designed to prioritize user-friendliness and flexibility, offering a comprehensive and streamlined access control solution for your convenience.
The device cabinet is fitted with a comprehensive connection diagram on the inside of the cabinet door, providing clear and concise guidance on reader, input, and output connections. A Quickstart Guide is also provided with the unit.
Communication with the SDC-650 or SDC-620 Controllers is seamless, facilitated by the RS-485 Reader Network through the onboard connector. Each device is assigned a unique device address via an onboard rotary switch. Once communication is established, managing access control configurations for doors, readers, and more becomes effortless using the intuitive SACS Connect Software.
For a trouble-free installation experience, diagnostic LEDs are strategically placed close to their relevant terminals, providing valuable support and guidance. End-of-line resistors can be effortlessly integrated into the RS-485 Reader Network circuit using the indicated jumpers, eliminating the need for external terminating resistors.
The dual-mode relays can be set as powered outputs or potential-free relays (using the indicated jumpers), for you to easily switch any lock or electrical device, ensuring maximum control and flexibility over your access control infrastructure.
Operation
The SEB-722 Remote I/O Expansion Board operates by connecting to the RS-485 Reader Network ports on the SDC-650 Multiple Door Controller or SDC-620 Ethernet Controller and expands the remote input, output and access control capabilities of the Controller. Once connected and configured, the SEB-722 can receive inputs from external devices, such as door contacts or motion sensors, and send outputs to devices such as locks or buzzers.
In addition, it facilitates direct connections to up to 4 additional RS-485 Readers and 2 Wiegand devices via the slave network and Wiegand interfaces for controlling access at the remote location.
About the product
About the Product
The SEB-722 Remote I/O Expansion Board is a versatile addressable expansion device designed to extend the Input and Output capabilities of the SDC-650 Multiple Door Controller and SDC-620 Wiegand Door Controller. The device integrates seamlessly with the RS-485 Reader Network of these controllers, as well as other RS-485 devices, providing additional flexibility when designing and expanding an access control system.
The SEB-722 allows inputs and outputs to be relocated closer to the door, helping to reduce potential voltage drops when the controller is installed further away from the access point. This enables more efficient system installations by providing remote door control capabilities and improving the overall flexibility of access control deployments.
With three distinct reader configurations available, the SEB-722 Remote I/O Expansion Board offers enhanced adaptability for various access control applications and operational requirements. The device allows installers to customise system layouts while maintaining reliable communication between connected devices.
The unit features 2 relay outputs with internal and external operating modes, as well as 4 programmable digital inputs, providing comprehensive control and monitoring functionality for connected access points and devices.
In addition, the SEB-722 supports direct connections to up to 4 additional RS-485 devices through the slave network and up to 2 Wiegand devices through the Wiegand interfaces. This allows for the integration of up to 16 devices with the SDC-650 or SDC-620 Controllers, providing a scalable solution that can easily adapt to growing access control requirements.
The SEB-722 Remote I/O Expansion Board is an ideal solution for expanding system capabilities, improving installation flexibility, and enhancing the overall performance of your access control infrastructure.
