ABB 3BHB003688R0101

Product introduction

The 3BHB003688R0101 is a multi-output industrial power module from ABB, designed to deliver stable and reliable power to a variety of control system components in demanding industrial environments. As a key component in ABB’s power supply portfolio, 3BHB003688R0101 provides three regulated DC outputs (5 V, 12 V, and 24 V) to support diverse devices such as PLCs, I/O modules like the NBIO-31 3BSE011337R1, and communication interfaces.

Engineered for robustness, 3BHB003688R0101 combines high efficiency with comprehensive protection mechanisms, ensuring continuous operation even in harsh conditions. Its compact design allows easy integration into crowded control cabinets, while the universal input range (110-230 V AC) enables global deployment without voltage adjustment. Whether powering control systems in manufacturing plants, process facilities, or energy production sites, 3BHB003688R0101 serves as a critical backbone, delivering consistent power to maintain system integrity and minimize downtime.

Core advantages and technical highlights

Triple-output versatility: 3BHB003688R0101 provides three isolated DC outputs (5 V, 12 V, 24 V) in a single unit, eliminating the need for multiple standalone power supplies. This integration reduces cabinet space by up to 40% compared to using separate 5 V and 24 V modules. In a typical control system, the 5 V output can power logic circuits of a PLC, 12 V can drive sensors, and 24 V can operate actuators—all from one compact module, simplifying wiring and reducing potential failure points.

Enhanced load handling: With a total power output of 260 W (20 A at 5 V, 10 A at 12 V, 8 A at 24 V), 3BHB003688R0101 can support multiple high-power devices simultaneously. Unlike lower-capacity modules such as the AFP9075355 3BHS537443, which focus on 24 V alone, this model’s multi-voltage design makes it ideal for powering mixed-component systems like a UFC760BE142 3BHE004573R0142 control unit paired with its associated sensors and actuators.

Adaptive protection mechanisms: 3BHB003688R0101 features per-output overcurrent protection, ensuring that a fault in one voltage rail (e.g., a shorted 24 V actuator) doesn’t disrupt 5 V logic supplies. The module also includes overtemperature shutdown with automatic recovery, preventing damage during extreme ambient conditions. In a steel mill control cabinet, this protection prevents a 12 V sensor short from disabling the 5 V power to critical safety relays, maintaining operational safety.

High efficiency and low noise: With efficiency exceeding 88% at full load, 3BHB003688R0101 minimizes energy waste and heat generation, reducing cooling requirements in enclosed cabinets. Its low ripple output (≤50 mV) protects sensitive electronics like communication modules from noise-induced errors, ensuring reliable data transmission in systems using Profibus or Ethernet/IP protocols. This stability is particularly valuable in precision applications such as semiconductor manufacturing, where voltage fluctuations could corrupt process data.

Typical application scenarios

In a pharmaceutical production facility, 3BHB003688R0101 powers a control system for a batch mixing unit. The 5 V output supplies a PLC’s central processing unit, 12 V drives temperature and pressure sensors, and 24 V operates solenoid valves and 搅拌器 (stirrer) motors. During a sudden 24 V short caused by a valve malfunction, the module’s per-output protection isolates the fault, allowing the PLC and sensors to continue operating—preventing loss of critical batch data and enabling a controlled shutdown. The universal input ensures compatibility with the facility’s 230 V AC grid, while the IP20 rating protects internal components from dust in the cleanroom environment.

In an automotive assembly line’s robot control cabinet, 3BHB003688R0101 provides power to a UFC760BE142 3BHE004573R0142 control unit, NBIO-31 3BSE011337R1 digital I/O module, and various sensors. The 5 V and 12 V outputs handle low-voltage logic and sensor signals, while 24 V powers relay coils and gripper actuators. The module’s high efficiency reduces heat buildup in the enclosed cabinet, extending component lifespan, and its low ripple ensures accurate sensor data transmission—critical for precise robotic welding operations.

Installation, commissioning and maintenance instructions

Installation preparation: Mount 3BHB003688R0101 on a 35 mm DIN rail in a control cabinet, ensuring 60 mm clearance above and below for airflow. Connect input power (110-230 V AC) using 2.5 mm² cable, protected by a 5 A time-delay fuse. Wire outputs to terminal blocks using appropriate gauge cables: 1.5 mm² for 5 V (high current), 1 mm² for 12 V, and 1.5 mm² for 24 V. Ground the module via the dedicated earth terminal. Verify input voltage matches the supply before energizing. Use a torque screwdriver set to 0.8 Nm for all connections. Power off the input supply during installation.

Maintenance suggestions: Inspect 3BHB003688R0101 quarterly for loose connections, dust accumulation, and LED status (power: green, fault: red per output). Clean ventilation slots with compressed air to prevent overheating. Measure output voltages semi-annually under load to ensure they remain within ±2% of nominal values (5 V: 4.9-5.1 V, 12 V: 11.76-12.24 V, 24 V: 23.52-24.48 V). Test protection features annually by simulating overloads on each output and verifying proper shutdown/recovery. If a fault persists, replace the module with an ABB-certified unit to maintain system compatibility and safety.
