Product Performance
Compatible with MICOM series relay protection devices and PLC control systems, adopting dual-mode compatible power supply of 24VDC/110–250VAC, with a rated power consumption of less than 6W, it is energy-saving and efficient, can adapt to the 24-hour uninterrupted operation needs of various industrial scenarios, and has high operational stability.
As a single-phase overcurrent protection relay, it integrates an instantaneous protection element, complies with IEC 60255 standards, can accurately detect single-phase circuit overcurrent faults, realize instantaneous protection actions, quickly cut off fault circuits, and avoid equipment damage.
It also has the function of an auxiliary control module, which can be used as an intermediate relay to realize signal transmission inside the PLC. Its normally open and normally closed contacts can be used infinitely during programming, clearly optimizing the logical structure of the program without directly driving external loads.
Equipped with RS485 serial interface and Ethernet port, it supports mainstream communication protocols such as IEC 60255 and Modbus RTU/TCP, and can be seamlessly connected to industrial automation systems and monitoring platforms to realize real-time transmission of fault signals and operating status.
Supports the input and output processing of analog signals (4-20mA) and digital signals, has high-precision signal conditioning functions, can accurately collect circuit operating parameters, and provide reliable data support for protection actions and signal transmission.
With a protection level of IP65, it has excellent dustproof and waterproof performance, can be directly applied to outdoor and dusty, humid industrial sites without additional protective measures, effectively protecting internal components and extending product service life.
The operating temperature covers -40℃ to +70℃, and the storage temperature range is -40℃ to +85℃, with extremely strong environmental adaptability. It can operate stably in extreme environments such as alpine and high temperature without performance degradation, meeting the needs of harsh industrial scenarios.
Integrated with complete fault diagnosis and LED status indication functions, it can real-time monitor the module operation status and fault conditions, clearly display delayed actions and instantaneous actions through LED lights, facilitating staff to quickly troubleshoot faults and carry out tests.
Built-in non-volatile storage function, which can save the LED indication status of delayed and instantaneous actions, without losing key information even if the power is interrupted, and can reproduce the instantaneous fault status after the power is restored.
Adopting standardized modular design, supporting standard rail and built-in slot mounting for relay protection devices, it is easy to install, can be directly integrated into existing systems without additional adaptation and debugging, consistent with ALSTOM’s modular design concept.
Complies with international certification standards such as IEC 60255, CE and UL, the product quality and safety performance meet the specifications of the global industrial protection and control field, with high protection accuracy and reliable operation, no malfunction hidden dangers.
