ABB NDBU-95 Branching Unit

Power consumption: The typical power consumption is less than 5 W for low-power industrial environments.

Channel isolation: The channel-to-channel electrical isolation voltage is ≥500 V AC, and has strong anti-interference ability.

Protocol support: Compatible with mainstream industrial protocols such as PROFIBUS DP and Modbus RTU, this product can be seamlessly connected to PLC systems such as Siemens, Rockwell, etc.

Faster transmission rate: The transmission rate of PROFIBUS DP can reach up to 12 Mbps, thus supporting high-speed data transmission.

Mounting way: Mounting on rail (according to EN 50022), for fast plug-in and unplug

Wide operating temperature range: -25°C to 70°C (for severe industrial environment adaptability).

Relative humidity: 5% to 95% (non-condensing).

Main Body: 5g (10 – 150 Hz) Vibration (MIL-STD-810) 10g Shock (MIL-STD-810) Strong resistance to mechanical stress

Justify for I/O: Digital input/output like 24 V DC signal, some models can expand analog quantity (need to confirm for model version).

No of channels: Standard 16 digital in/out channels, modularly expandable.

Fault diagnosis: There is a built-in LED indicator that can show the working status in real time, ABB NDBU-95 supports short circuit, overload detection and automatic protection.

dcc| Redundancy support: dual power supply redundant design, ensure system continuity. 

Adaptable to multiple brands: and compatible with mainstream PLC systems such as A-B, Schneider, GE, Siemens, etc, you can reduce integration costs.

Protocol conversion: ABB NDBU-95 enables transparent conversion from PROFIBUS to other protocols, facilitating the integration of multi-protocol systems.

3. High-precision signal processing

Resolution : ABB NDBU-95 with 12-bit analog resolution (applicable if analog channels are supported), usual acc. ±0.1% F.S.

Ripple suppression: >60 dB (50/60 Hz), output signal stable and smooth.

Removable screw terminals: ABB NDBU-95 has 24-12 AWG wire screw terminals, easy to plug in and pull out, reducing maintenance time.

Modular design: ABB NDBU-95 supports hot plug and unplug, convenient to replace the faulty module.

Energy Management: Connection to the power monitoring system, to achieve data collection and remote control.

Smart Building — These are leveraged in building automation systems that allow centralized control of lighting, HVAC and other devices.
