III. Electrical Parameters

Input Specifications

The module's rated input voltage is DC 24V, with a voltage allowable fluctuation range of 10% of the rated value. The maximum input current is 3.5A, and it integrates a 6.3A slow-acting fuse for basic protection of the input circuit. The module has an independent buffer voltage input terminal, supporting 8V to 30V DC voltage connection, mainly used in combination with external battery modules to achieve controller data power-off retention.

Output Specifications

The total output rated power of the module is 50W, with a peak output power of up to 60W. It can simultaneously generate multiple DC voltages required by the system backplane, including 5V, ±15V, etc., providing unified power supply for all CPUs, I/O, communication, counting, bus modules on the backplane. The module integrates expansion interfaces, allowing external expansion backplanes to be connected to provide power support for remote expansion sites, meeting the multi-point expansion requirements of the system.

IV. Functional Features

Basic Power Supply Function

The output voltage and current of this module are optimized for System 2005 platform hardware characteristics. The output has low ripple and strong voltage stability, which can adapt to modules with high requirements for power quality such as high-speed counting, bus communication, and analog signal acquisition, avoiding data anomalies, communication interruptions, or control failures due to voltage fluctuations. All front-end hardware of the entire system is centrally powered by this module through the backplane, resulting in simple wiring and high system integration.

Power-off Data Retention Function

When using a buffer voltage and backup battery module in combination, in the event of a main power outage, it can seamlessly switch the power supply circuit, continuously providing power to the internal persistent memory of the controller, ensuring that running parameters, process data, and intermediate variables are not lost. After the equipment is powered on again, it can resume the original working state, reducing the impact of production interruptions.

System Expansion Function It has its own expansion bus interface and supports multi-level backplane expansion. Each independent expansion backplane can be powered by the same model power module, allowing for flexible construction of large-scale distributed I/O control systems, meeting the power supply requirements of large production lines and multi-unit interlinked equipment.

Status monitoring function

The front of the module is equipped with multiple LED status indicators, corresponding to power connection, normal operation, fault alarm, etc. On-site personnel can directly judge the working status of the module. At the same time, a relay-ready contact is provided, and the contact closes when the power output is normal, allowing for external sound and light alarms, external interlock circuits, and remote status monitoring and safety linkage.

V. Protection Mechanism

The module integrates multiple industrial-grade protection functions. The input circuit has reverse polarity protection and overvoltage protection to avoid wiring errors and external voltage abnormalities that may cause module burnout. The output circuit is equipped with overcurrent protection and short-circuit protection. When a short circuit occurs in the rear-end module or the load is abnormal, the module automatically limits the output current, and can automatically return to normal operation after the fault is resolved, without the need for manual restart. The overall circuit is designed with anti-electromagnetic interference, capable of withstanding electromagnetic interference generated by industrial equipment such as frequency converters and motors, and is suitable for complex working conditions such as machine tools, textiles, packaging, and injection molding.

VI. Mechanical Structure and Heat Dissipation

The overall size of the module is compatible with the System 2005 standard backplane. Due to the dual-slot design, the width is greater than that of conventional I/O modules, and the overall weight is approximately 1.2kg. It uses natural air cooling, and no additional cooling fans are required during operation. When in use, a reasonable ventilation space must be reserved around the module to ensure the cooling effect. It supports both horizontal and vertical installation methods, fully compatible with standard industrial control cabinet layouts.

VII. Application Domains and Application Scenarios

This module is specifically designed for the Bechtel System 2005 control system. The primary application scenario is the overall power supply for this series of main control stations, providing basic power for the CPU, digital and analog I/O, communication modules, and motion control modules. Secondly, it can be used as an expansion station power supply unit to supply power to distributed remote I/O backplanes, building medium and large-scale automation control systems. When an external battery module is combined, it is applied to production equipment with high requirements for data storage continuity, achieving power protection in the event of power failure. It is also commonly used in the renovation projects of old Bechtel equipment, replacing aging and faulty power modules to restore the stability of the entire equipment and extend the overall service life of the equipment. Typical application equipment includes various processing machines, textile machinery, printing equipment, packaging lines, small injection molding equipment, and process monitoring control systems.
