Siemens Redundancy Module For Use With SITOP Series, 24V DC Supply Voltage, 40A Current Rating - 6EP1961-3BA21 Maintain uninterrupted power supply in critical industrial operations with this redundancy module from Siemens. It's designed for use with two SITOP power supply units and it monitors the circuit and ensures that only one works at a time. When a fault occurs in one power unit, the module detects and bypasses it, transitioning swiftly to the other, ensuring smooth operation of your equipment. As the housing comes with clips that snap onto DIN rails, installation is easy and tool-free. With a current rating of 40A, this module is a practical choice for high-power applications. • Light weight of 500g for easy handling and minimal strain on equipment
• Compact dimensions of 125 (H) x 70 (W) x 125mm (D) make it suitable for setups with limited space
• Wide operating temperature range between 0°C and +60°C for use in demanding conditions How do I monitor this device? This redundancy module has two LED indicators – a green one that shows that both input voltages are above switching level and a red one that indicates that at least one is below normal. These make monitoring and troubleshooting easy.
