Product Performance

Compatible with railway electronic control equipment, MICOM series relay protection devices and PLC control systems, adopting dual-mode compatible power supply of 24VDC/110VAC, 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 railway and 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, avoid equipment damage, and ensure the safety of railway and industrial circuits.

It also has the function of an auxiliary control module, which can be used as an intermediate relay to realize signal transmission inside PLC and railway electronic equipment. 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, and supporting auxiliary control of railway traction and braking systems.

Equipped with RS485 serial interface, Ethernet port and CAN bus interface, it supports mainstream communication protocols such as CAN, EtherCAT and RS485, and can be seamlessly connected to railway electronic control systems, industrial automation systems and monitoring platforms to realize real-time transmission of fault signals, operating status and railway equipment data.

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 railway equipment status data, and provide reliable data support for protection actions, signal transmission and railway system control.

With a protection level of IP65, it has excellent dustproof and waterproof performance, can be directly applied to outdoor, railway lines 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, high temperature and strong electromagnetic interference without performance degradation, meeting the needs of railway and 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, and improving the operation and maintenance efficiency of railway and industrial equipment.

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, providing support for fault traceability.

Adopting standardized modular design, supporting standard rail and built-in slot mounting for railway electronic equipment, it is easy to install, can be directly integrated into existing railway and industrial 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 railway electronic control and industrial protection field, with high protection accuracy and reliable operation, no malfunction hidden dangers, and suitable for use in key railway scenarios.
