Siemens Redundancy Module for use with SITOP, SITOP PSE202U Series, 24V DC, 40A Current Rating 6EP1961-3BA21

Siemens 6EP1961-3BA21 Redundancy Module is designed for use with SITOP power supplies, specifically within the SITOP PSE202U series. It operates at a 24V DC supply voltage and supports a current rating of 40A, making it suitable for high-power industrial applications requiring reliable and continuous power.

This module monitors two SITOP power supply units, ensuring that only one supply is active at a time. If one unit fails, it quickly switches to the other, preventing downtime and protecting connected equipment from power interruptions. Its lightweight housing, weighing approximately 500 grams, and compact dimensions of 125 mm height, 70 mm width, and 125 mm depth, enable installation in space-constrained panels.

The redundancy module mounts easily on DIN rails without requiring tools, facilitating quick setup and maintenance. Its operating temperature range from 0°C to +60°C allows dependable operation in various industrial environments, including manufacturing and automation systems.

For user convenience and operational monitoring, the device features two LED indicators: a green LED indicating both input voltages are above the switching threshold and a red LED signaling a voltage below normal levels in at least one input. These visual signals aid in fast troubleshooting and maintenance.

Certified to meet CSA, CE, and UL standards, this Siemens redundancy module delivers reliable performance for industrial power supply backup needs. It originates from Romania, ensuring compliance with international manufacturing standards.

Maintains continuous operation by switching between two SITOP power supplies. Compact and lightweight with dimensions 125 x 70 x 125 mm and weight of 500 grams. Easy DIN rail mounting with tool-free installation. Wide operating temperature range from 0°C to 60°C for demanding environments.

Includes dual LED indicators for monitoring input voltage status and fault detection. Meets CSA, CE, and UL standards for industrial safety and quality.
