Bosch B308 — 8-Output Expander Module, SDI2

Eight Form C relays on one SDI2 board for Solution 2000, 3000 and G-Series panels. Each relay is rated 1A at 5–24 V DC, and the SDI2 bus supports runs of up to 305m — so the outputs can be sited a long way from the panel, right beside whatever they are switching.

Key Details

• Eight Form C relays — Twice the outputs of a four-way expander on a single bus address.
• 1A at 5–24 V DC — Enough to drive most sirens, strobes, locks and relays directly without an interposing contactor.
• 305m bus runs — SDI2 reaches right across a large building, so outputs go where the load is.
• Very slim at 15mm — A 73.5 x 127 x 15mm board that fits a shallow enclosure.
• Spans three panel families — Solution 2000, Solution 3000 and G-Series on one part number.

Where It Fits

The output expander for SDI2-based systems needing more than a handful of controlled circuits. On a Solution 16i, 144 or 6000 running the LAN bus, the CM710B is the corresponding part.
