S-093N 3BHB009885R0021

Product Introduction

The 3BHB009885R0021 (market name: S-093N) is a high-reliability industrial switching power supply module from ABB, specifically engineered to deliver stable, regulated power to ABB’s distributed control systems (DCS)—such as the 800xA series—and programmable logic controllers (PLCs). As a critical “power backbone” for industrial automation systems, the 3BHB009885R0021 (S-093N) integrates dual-input compatibility (AC/DC) and robust protection features, ensuring uninterrupted power delivery even in unstable grid conditions.

This module converts wide-range input voltages (100-240 V AC or 110-300 V DC) into precise 24 V DC power— the standard voltage for most industrial field devices like sensors, actuators, and I/O modules. The 3BHB009885R0021 (S-093N)’s high efficiency (≥88%) and wide operating temperature range make it suitable for harsh industrial environments, from manufacturing plants to offshore platforms. By maintaining ±0.5% output voltage accuracy, it prevents voltage fluctuations from disrupting sensitive control logic, directly safeguarding system uptime and process stability.

Core Advantages and Technical Highlights

Dual-Input Flexibility for Uninterrupted Power: The 3BHB009885R0021 (S-093N) supports both AC (100-240 V) and DC (110-300 V) input, eliminating the need for separate power supplies in mixed-grid environments. For example, in regions with frequent AC power outages, the module can seamlessly switch to DC backup power (e.g., from a battery bank) without disrupting connected DCS/PLC systems—critical for applications like chemical reactor control, where power interruptions could cause safety hazards.

Precision Regulation & High Efficiency: Equipped with advanced PWM (Pulse-Width Modulation) technology, the 3BHB009885R0021 (S-093N) maintains ±0.5% output voltage accuracy, even under varying load conditions (from 10% to 100% of rated current). This precision ensures consistent performance of ABB 800xA I/O modules and sensors, avoiding data errors or device malfunctions caused by voltage drift. Additionally, its ≥88% efficiency reduces energy waste and heat generation, lowering long-term operational costs and extending the module’s lifespan.

Rugged Design for Harsh Environments: The 3BHB009885R0021 (S-093N) operates reliably in temperatures ranging from -25 °C to 70 °C, with built-in thermal derating to protect components at high ambient temperatures. Its aluminum alloy housing enhances heat dissipation, while conformal coating on internal circuits resists dust, moisture, and chemical vapors—ideal for food processing plants (high humidity) or oil refineries (corrosive fumes). Unlike consumer-grade power supplies, it meets IEC 61010-1 CAT II safety standards, ensuring protection against electrical surges common in industrial grids.

Comprehensive Protection Mechanisms: The 3BHB009885R0021 (S-093N) includes multi-layer protection to prevent damage to itself and connected equipment. Overload protection triggers at 120-150% of rated current (e.g., if a shorted sensor draws excess power), while overvoltage protection cuts output if voltage exceeds 28-30 V DC (preventing damage to 24 V DC actuators). Short-circuit protection uses a fast-acting current limiter to avoid fire risks, and the module automatically recovers once the fault is resolved—reducing the need for manual resets and minimizing downtime.

Typical Application Scenarios

In ABB 800xA DCS-based power generation plants (e.g., natural gas-fired power stations), the 3BHB009885R0021 (S-093N) serves as the primary power source for boiler control I/O modules and safety interlock systems. Its dual-input capability allows it to draw power from the plant’s main AC grid or a backup DC battery bank—critical during grid fluctuations that could disrupt turbine speed control or fuel valve operation. The module’s ±0.5% voltage accuracy ensures precise signal transmission from pressure transducers to the DCS, enabling tight control of steam pressure and preventing turbine overspeeding.

In automotive assembly plants using ABB robotic arms and PLCs, the 3BHB009885R0021 (S-093N) powers vision sensors, conveyor belt controllers, and robotic end-effectors. Its rugged design withstands the high temperatures (up to 65 °C) near welding stations and resists metal dust accumulation, while overload protection prevents damage if a robotic arm jams (drawing excess current). The module’s DIN rail mounting simplifies integration into existing control cabinets, reducing installation time for production line expansions.

In marine automation systems (e.g., cargo ship navigation and engine control), the 3BHB009885R0021 (S-093N) operates in harsh conditions—including salt spray, vibration (up to 5 g), and wide temperature swings (-20 °C to 60 °C). It powers ABB’s marine PLCs and navigation sensors, with its dual-input design using both the ship’s AC generator and DC emergency power. The module’s high MTBF (2.5 million hours) minimizes maintenance in remote marine environments, where 备件 replacement is logistically challenging.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing the 3BHB009885R0021 (S-093N), ensure the control cabinet is grounded per IEC 60439-1 standards and free of flammable materials. Verify the input power matches the module’s range (100-240 V AC or 110-300 V DC) to avoid damage. Required tools include a torque screwdriver (for DIN rail mounting, torque setting: 0.8-1.2 N·m), wire crimpers (for terminal connections), and a multimeter (to test input voltage). Use 14 AWG (2.5 mm²) wires for input and 16 AWG (1.5 mm²) wires for output; leave 50 mm (2 in) of clearance around the module for heat dissipation. Always disconnect power before wiring to prevent electrical shock.

Maintenance suggestions: For daily maintenance of the 3BHB009885R0021 (S-093N), check the LED status lights (green = normal operation, red = fault) during shift handovers. Clean the module’s vents monthly with compressed air (max 50 psi) to remove dust—clogged vents cause overheating and reduce efficiency. Every 6 months, use a multimeter to verify output voltage (should be 24 ±0.12 V DC) and test protection features (e.g., short-circuit one output terminal briefly to confirm the module shuts down and recovers). If a fault occurs, refer to the 3BHB009885R0021 (S-093N) user manual to troubleshoot—common issues include loose input wires (check terminal torque) or overloads (reduce connected load). Replace failed modules with ABB-approved spares only, as third-party alternatives may not meet safety standards.
