Radionix B308 SDI2 8-Output Expansion Module

Extend an SDI2 physical-security installation with eight additional output points for panel-directed devices. Radionix B308 serves as an SDI2 8-output expansion module, placing output expansion on the existing system bus rather than requiring a separate control platform. It provides a defined expansion point where the base controller’s existing connections do not cover the required field functions. Use the module where an SDI2 system needs additional controlled connections at a panel or enclosure. Eight outputs make the unit relevant to sites with multiple field devices that require panel control, including signaling, annunciation, and other output-actuated equipment. Its SDI2 interface keeps the module within the same control-system architecture as the host equipment instead of introducing an unrelated output platform. Selection turns on the required output count and an existing SDI2 architecture. B308 supplies eight outputs, distinguishing it as an output-capacity expansion component rather than a standalone security platform. Verify host-system support, enclosure space, output electrical requirements, field-device wiring, and installation instructions before integration. Those factors determine how the module is applied without changing its core role as an SDI2 output expansion component.
