BNW5i-S

The BNW5i-S is a bus voltage monitoring unit designed to supervise supply voltage in three-phase power networks and has been developed for use in emergency lighting systems. In addition to conventional network monitoring, the device provides additional inputs for monitoring further conditions within the installation.

The device detects both individual phase failures and voltage levels falling below defined thresholds, enabling reliable assessment of the power supply status. In addition, several inputs are available that can be used to monitor light switches, circuit breakers or other external signals.

Integration is achieved through a bus connection, allowing the voltage monitoring unit to be incorporated into centralized systems. Each device is assigned a unique address via address selectors, supporting a structured system architecture.

DIN rail mounting enables straightforward integration into switch cabinets and electrical distribution systems. The extended functionality allows additional monitoring tasks to be handled directly within a single device.

For planners, the BNW5i-S provides a combined solution for power supply monitoring and status acquisition. Installers benefit from a clearly structured installation concept and a reduced number of components.

• three-phase monitoring enables reliable supervision of the power supply
• phase failure detection enables rapid response to critical conditions
• undervoltage monitoring enables early fault detection
• additional inputs enable monitoring of switching and circuit breaker states
• bus communication enables integration into centralized emergency lighting systems
• the addressable structure enables clear system identification
• DIN rail mounting enables straightforward installation within switch cabinets
• the combination of multiple functions reduces the need for additional components

The BNW5i-S expands conventional power supply monitoring with additional signal acquisition capabilities, providing an integrated solution within emergency lighting systems. For planning purposes, this reduces interface complexity by combining multiple functions within a single device.

Structured bus integration supports a clear system architecture and simplifies the planning of complex installations. Through its addressable structure, monitoring points can be clearly defined and uniquely assigned within the system.

As the device is installed within the switch cabinet, it has no impact on architectural design and enables completely technical integration in the background.

Installation is carried out via DIN rail mounting and follows established installation standards. This allows the device to be integrated easily into existing electrical distribution systems.

The bus connection enables straightforward integration into the overall system. Using the address selectors, each device can be uniquely identified, simplifying installation and commissioning.

The additional inputs allow further signals to be integrated without requiring additional components. This reduces installation effort and simplifies wiring.

For installers, this means a structured implementation, fewer components and a more efficient installation process.
