The Siemens 3RK1408-8KE00-0AA2 is a specialised ground fault module designed to enhance the safety and reliability of automated systems. This compact module is part of the AS-Interface system and is engineered to detect ground faults within an AS-i network, ensuring the integrity of your control system's electrical setup.
With its slim 22.5 mm width, the module is an ideal choice for space-constrained installations, and it can be easily mounted on a standard rail or directly onto a wall. The module operates effectively within a voltage range of 24 to 48 V DC and is capable of handling a current of up to 1 A for DC-12 and 500 mA for DC-13 at 24 V.
One of the key features of this module is its ability to monitor for earth faults between 10% and 90% of the AS-i voltage, providing a broad detection range that ensures prompt identification of potential issues. The module does not require its own AS-Interface address, which simplifies integration and maintenance.
The 3RK1408-8KE00-0AA2 is equipped with built-in polarity reversal protection, which safeguards the module against incorrect wiring, further enhancing system safety. Additionally, it offers two signalling outputs and a remote reset capability, which allows for easy troubleshooting and resetting of the system from a remote location.
This ground fault module is designed to withstand harsh industrial environments, with an operational temperature range of -25 to +70 degrees Celsius, making it suitable for a wide range of applications. It is also noteworthy that if repeaters are used within the network, a ground fault detection module is required for each AS-Interface segment, ensuring comprehensive protection throughout the system.
Overall, the Siemens 3RK1408-8KE00-0AA2 ground fault module is a robust and reliable component that provides essential protection for your AS-i network, contributing to the overall safety and efficiency of your automated processes.

What is the function of the AS-i ground fault module?
The AS-i ground fault module is designed to detect ground faults in an AS-Interface network. It monitors the insulation resistance between the AS-i cable and ground, helping to ensure the integrity and safety of the network.
Can this module detect overvoltage conditions?
No, the module is not equipped to detect overvoltage conditions. Its primary function is to monitor for ground faults within the AS-Interface system.
What type of electrical connection does this module use?
The module uses screw-type terminals for its electrical connections, providing a secure and reliable means of connecting the module to the AS-Interface network.
Is an AS-i address required for this module?
No, the 3RK1408-8KE00-0AA2 module does not require its own AS-Interface address as it is solely dedicated to monitoring the AS-Interface network for ground faults.
What is the operating temperature range for this module?
The operating temperature range for the module is from -25°C to +70°C, allowing it to function effectively in a variety of industrial environments.
How is the module protected against polarity reversal?
The module has built-in polarity reversal protection to prevent damage from incorrect wiring, enhancing its reliability and longevity in the field.
What should be done if repeaters are used in the AS-Interface network?
If repeaters are used in the network, a ground fault detection module must be used for each AS-Interface segment. This means the number of AS-Interface power supply units should equal the number of ground fault detection modules.
How can the endurance of the relay in the module be increased?
The endurance of the relay can be increased by connecting inductive loads using freewheel diodes. This helps to protect the relay from voltage spikes and extends its operational life.
What is the width of the module, and how is it mounted?
The module has a width of 22.5 mm and can be mounted on a standard rail or directly onto a wall, providing flexibility in installation.
What is the rated operational voltage for this module?
The rated operational voltage for the module is between 24 V and 48 V DC, accommodating a range of industrial power supply standards.
