Bosch B208 8-Input Expansion Module, SDI2

Increase monitored inputs on your security control panel without a major retrofit. The Bosch B208 8-Input Expansion Module is a compact control panel module designed to add eight fully supervised points for enhanced security, surveillance, and facility monitoring. Built for commercial, industrial, and institutional installations, the B208 connects over the SDI2/SD12 bus using terminal or interconnect cable for dependable, low-latency communication with Bosch panels.

Installers benefit from easy-to-read address switches and simple interconnect wiring that reduce labor time. The module supports programmable input functions so you can map each point to alarm, tamper, or supervisory responses that match your site policy, reducing nuisance alarms. With a 12V DC input and a modest 35 mA draw, the B208 provides efficient expansion while maintaining panel power budgets. NDAA and RoHS compliance make it suitable for government and enterprise projects.

For integrators and security managers needing to scale monitoring capacity quickly, the Bosch B208 offers a reliable, code-compliant solution. Add the B208 to your next project to expand panel monitoring and streamline surveillance deployments.
