ABB PPD113B01-25-111000 3BHE023784R2530 Controller

Protection Functions: Referencing products of the same series, it may be equipped with multiple protection mechanisms, enabling real-time monitoring and protection against faults such as overload, short circuit, overvoltage, and undervoltage in power systems. It can quickly detect abnormal conditions and take protective actions like tripping to ensure the safe operation of power equipment and systems.

Control Functions: It may realize control over certain equipment in power systems, such as on/off control of switching equipment, by receiving external signals or executing corresponding control operations based on preset logic, facilitating the automated operation and management of power systems.

Measurement Functions: It may be capable of measuring key parameters in power systems, such as current, voltage, and power, providing data support for operational monitoring and fault analysis of power systems.

Memory: The storage capacity is speculated to be around 17KB. However, similar products may have different capacity specifications, and the specific value should be determined based on the actual product.

Communication Interfaces: It may be equipped with an RS232 communication interface and support common communication protocols such as Modbus and Profibus for communication and data interaction with other devices or systems. However, it may also support other types of communication interfaces and protocols, subject to the actual configuration of the product.

Rated Voltage: It is speculated to be 24V DC, a common voltage class in the field of industrial control. However, other voltage specifications such as 110V AC or 220V AC cannot be ruled out.

Rated Current: As previously speculated, the rated current of this product may be around 10A–20A. However, the actual rated current value should be determined based on the detailed technical data of the product, as different application scenarios and design requirements may lead to variations in the rated current.

Overload Protection: It can detect current exceeding a certain proportion of the rated load and trigger protective actions within a set time. The specific overload multiple and action time can be set according to actual needs.

Short Circuit Protection: When a short-circuit fault in the circuit is detected, it should be able to cut off the circuit in an extremely short time (usually in milliseconds) to prevent equipment damage and the expansion of accidents.

Overvoltage Protection: An overvoltage protection threshold can be set. When the input voltage exceeds this threshold, automatic protective measures such as power power cut-off or voltage reduction will be taken. The protection threshold may be between 110% and 130% of the rated voltage.

Undervoltage Protection: When the input voltage is lower than the set undervoltage threshold, protective actions will be triggered to avoid equipment failures or damage caused by operation at too low a voltage. The undervoltage threshold may be between 70% and 90% of the rated voltage.

Current Measurement Range: It may cover a range from tens of milliamps to tens of amperes or even higher, with a measurement accuracy typically reaching ±0.5%–±1%.

Voltage Measurement Range: It varies according to different rated voltages, generally capable of measuring voltage values within a certain range above and below the rated voltage, with a measurement accuracy of approximately ±0.5%–±1%.

Power Measurement Accuracy: It may be around ±1%–±2%, enabling accurate measurement of active and reactive power in power systems.

Robust and Durable: Made of high-quality materials and advanced manufacturing processes, it has strong anti-interference capability and adaptability to harsh environments, ensuring stable operation in industrial settings, reducing the probability of failures caused by environmental factors, and improving equipment reliability and service life.

Compact Design: With a relatively compact structural design, it occupies a small space, facilitating installation in various power equipment cabinets, helping to save installation space and improve space utilization.
