Specification & Description
The Siemens 6AG1961-3BA21-4AX0 is a high-performance redundancy module designed to enhance the reliability of your industrial power supply systems. This robust component is engineered to seamlessly decouple two SITOP power supplies, each with a maximum output current of 20A, ensuring a stable and uninterrupted power supply to your critical operations. With its ability to handle input and output voltages of 24V DC, this module is an essential safeguard against power inconsistencies.
Crafted for environments that demand resilience, the 6AG1961-3BA21-4AX0 comes with a conformal coating, providing an extra layer of protection against medial exposure that could potentially affect performance. The module's efficient design boasts an impressive efficiency rate of approximately 96.6%, minimising energy loss and maximising operational cost savings.
The unit is equipped with a clear status display featuring green and red LEDs to indicate operational status at a glance. The green LED signifies that both input voltages are above the switching threshold, while the red LED alerts you if at least one input voltage falls below this threshold. Additionally, the module offers a potential-free relay contact for signalisation, enhancing the monitoring capabilities of your power supply system.
With a compact width of 70mm and a height and depth of 125mm each, the Siemens 6AG1961-3BA21-4AX0 is designed for easy integration into your existing setup. It can be quickly snapped onto a DIN rail EN 60715 35x7.5/15 for a secure and reliable installation. The module's thoughtful design requires no lateral clearance, allowing for side-by-side mounting and efficient use of space within your electrical cabinet.
The Siemens 6AG1961-3BA21-4AX0 is a testament to reliability and efficiency, engineered to keep your industrial applications running smoothly without interruption. Its advanced features and protective measures make it a valuable addition to any system requiring a dependable power supply solution.
