Digital I/O module FBB-2DI1DO-R.230.AMP

Fieldbuswith relay output2 digital inputs

Product overview
The FBB-2DI1DO-R.230.AMP I/O module provides two digital inputs and one relay output. It is designed for decentralized switching tasks and for controlling motorized fire dampers (BSK) with integrated feedback (limit switches OPEN/CLOSED) or for general remote I/O collection.

Functions and operation
The module supports runtime measurement for motorized BSK. Each operation records total opening and closing times and measures dead time (time until a change of position is reported). Measured values are compared to maximum thresholds set during commissioning via the module properties.

Variants and options

• Supply voltage: 24 V or 230 V. On R.230 models the supply line (L) is switched through the relay contact to the digital output, so the output provides the supply voltage when active.
• Option AMP: Modules with the AMP option are fitted with specific plug connectors to accept pre‑fabricated, pluggable cables commonly offered for BSK actuators.

Applications
Decentralized switching tasks, control and feedback of motorized fire dampers (BSK), integration as remote I/O or data collector in building automation and fire safety systems.
