ABB 500PSM031MRB150038R1 894-030375D 136-011100H

Product Overview：

The ABB 500PSM03 1MRB 150038 R1 894-030375D 136-011100H is a high-efficiency industrial power supply module designed to provide a stable 24V DC power supply for critical automation systems. This module is part of the ABB S500 I/O series, known for its modular design and exceptional performance in harsh environments. It serves as the power backbone for PLCs, distributed control systems (DCS), and I/O devices in industries such as oil and gas, power generation, and manufacturing.

Its core function is to convert a wide-range AC input (85–264V AC) into a clean, stable 24V DC output with up to 90% efficiency, minimizing energy waste and heat dissipation. The 500PSM03 is unique in its ability to maintain output stability during voltage fluctuations, making it ideal for facilities with unstable grid power. The module’s compact design (135mm x 85mm x 25mm) allows for seamless integration into space-constrained control cabinets, and its rugged construction ensures reliable operation within a temperature range of -20°C to +60°C. By providing fail-safe power to mission-critical systems, the 500PSM03 reduces the risk of downtime and supports continuous production in applications where power interruptions could result in safety incidents or financial losses.

Technical Specifications：

Key Features and Benefits
Reliability in Harsh Conditions: The 500PSM03 utilizes galvanic isolation (1500Vrms) to prevent ground loops and electromagnetic interference, critical features in electrically noisy environments such as petrochemical plants. Its overload protection mechanism automatically shuts down the module in the event of a fault, preventing damage to connected equipment while maintaining system integrity.

Energy Efficiency: The module boasts an efficiency of ≥90%, minimizing power loss and thus reducing operating costs. Its wide input voltage range further enhances efficiency, eliminating the need for additional voltage converters for global deployments. Its low standby power consumption (<1W) also helps conserve energy when the system is idle.

Easy Integration: Designed for plug-and-play compatibility with ABB AC500 PLCs and S500 I/O modules, the 500PSM03 simplifies system setup. Its DIN rail mounting and color-coded terminals simplify installation, while hot-swappable functionality allows module replacement without shutting down the entire system. Application Scenarios
Oil and Gas Refineries: The 500PSM03 powers distributed control systems that manage distillation columns and pipeline valves. For example, it ensures stable operation of pressure transmitters and flow meters on offshore platforms, where voltage fluctuations are frequent. Its rugged design withstands the high vibration and corrosive environments typical of these environments.

Power Generation: In combined-cycle power plants, the module provides redundant power to gas turbine control systems, ensuring uninterrupted operation of combustion monitoring and steam turbine actuators. Its reliability is critical during load fluctuations or grid instability.

Manufacturing: The 500PSM03 powers robotic arms and quality control sensors, supporting automated assembly lines. For example, in automotive factories, it maintains constant voltage for torque tightening tools, ensuring compliance with safety standards.
