Description
Overview
Modules FBB-4DI2DO-R.230 provide four digital inputs and two relay outputs for decentralized switching. They are intended for control of motor-operated fire dampers with end-position feedback (end switches OPEN/CLOSED) and for general remote I/O datapoints.
Measured runtimes for motor-operated fire dampers
Measured runtimes are logged on each damper operation. The system records total opening and closing times and dead time (delay until movement is detected). Logged times are compared to commissioning maximum values stored in dedicated properties.

Measured runtimes for motor-operated fire dampers
Measured runtimes are logged on each damper operation. The system records total opening and closing times and dead time (delay until movement is detected). Logged times are compared to commissioning maximum values stored in dedicated properties.
Variants and options
- Supply voltage: 24V or 230V (on R.230 variant the supply voltage is switched to the relay outputs as the output signal).
- Option "AMP": variants with special connector sockets for connecting fire dampers with pre-assembled cables.
Additional notes
- FBB-4DI2DO.R.xxx and FBB-2DI1DO.R.xxx are available in different variants.
- Typical applications: decentralized switching, control of two fire dampers with end-switch feedback, general remote I/O datapoints.
Technical specifications
- Model: FBB-4DI2DO-R.230
- Function: 4 digital inputs, 2 relay outputs
- Relay output rating: 230V / 16A
- Supply voltage options: 24V or 230V (R.230 variant uses supply as relay output signal)
- Option: "AMP" connector variants available
- Suitable for: motor-operated fire dampers with end-switch feedback; general decentralized datapoints (Remote I/O)
- Measured runtime logging per damper run (open/close total time and dead time), compared to commissioning max values
