Nice XBA3HF Control Board (Compatible with MBAR / LBAR Series Barrier Systems)

Nice XBA3HF Control Board — MBAR LBAR Barrier Control Unit Spare Part

Nice XBA3HF is an original control board manufactured for MBAR and LBAR series barrier systems. Acting as the central brain of the system, this unit manages the motor's open-close cycles, coordinates connected safety devices, and executes all automation logic. Powered by a 230V AC mains supply, the board features an IP54 protection rating, providing resistance against dust and water splashes. Its operating temperature range spans from -20°C to +50°C, enabling continuous operation under harsh climatic conditions. The board includes a photocell input, flasher output, and a BlueBus communication line, through which external devices can be integrated into the system without additional wiring complexity. It supports automatic, semi-automatic, and manual operating modes, including RF receiver compatibility and wired button input. The main situations requiring replacement of the control board include: when the system fails to open or close, when it does not respond to remote control signals, when safety inputs fail to activate, or when burning marks or physical damage are detected on the board.

Replacing this control board is of MEDIUM difficulty. While removing the old board and installing the new one is not mechanically complex, it is necessary to connect the cables to the correct terminals on the board and to re-configure the programming parameters according to the current operating mode. A technician experienced in barrier system installation can perform this task without difficulty; however, those replacing this type of board for the first time are advised to consult Nice's technical documentation or seek support from an authorised service provider.

This control board is a fully original spare part manufactured by Nice S.p.A. Italy-based Nice S.p.A. is one of Europe's leading manufacturers in the field of automatic door and barrier systems, with products manufactured to international quality standards. Being an original Nice part safeguards your system's performance and safety certification; unlike aftermarket boards, full electrical compatibility with the MBAR and LBAR series is guaranteed.
