Siemens 3RK1408-8KE00-0AA2

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.
