Siemens 6EP1931-2FC21 | SITOP Redundancy Module – 24V DC, 40A for Parallel Power Supply Systems

Overview

The Siemens 6EP1931-2FC21 is a redundancy module from the SITOP series, designed to connect two 24V DC power supplies in parallel, ensuring uninterrupted power even if one supply fails. With a current rating of up to 40A, this DIN rail-mounted module is ideal for high-availability industrial systems, using diode-based decoupling to prevent feedback between connected supplies.

Key Features

  • Input Voltage: 24V DC

  • Rated Output Current: 40A

  • Number of Inputs: 2

  • Output Channels: 1

  • Redundancy Type: Passive (diode-based decoupling)

  • Mounting: DIN rail (EN 60715)

  • Status Indication: LED for input status

  • Reverse Polarity Protection: Yes

  • Operating Mode: Ensures uninterrupted power in case of failure of one supply

Technical Specifications

  • Part Number: 6EP1931-2FC21

  • Series: SITOP

  • Max Input Voltage Range: 20–30V DC

  • Voltage Drop (typical): ~0.5V at rated current

  • Current Rating: 40A continuous

  • Connection Type: Screw terminals

  • Dimensions (HxWxD): Approx. 125 × 70 × 125 mm

  • Ambient Temperature: –25°C to +70°C

  • Protection Class: IP20

  • Certifications: CE, UL, cULus, RoHS

Applications

  • Redundant power supply configurations

  • Industrial automation panels

  • Safety-critical control systems

  • Continuous process operations

  • Backup power for PLCs, HMIs, and field devices

Why Choose the 6EP1931-2FC21?

  • Ensures System Availability: Maintains output during power supply failure

  • High Current Capacity: Supports large industrial loads up to 40A

  • Compact DIN Design: Saves space in control cabinets

  • Plug-and-Play Setup: Simple wiring with no programming needed

  • Proven Siemens Quality: Trusted for mission-critical applications
