〖Product Detail〗

The Siemens 6ES5947-3UR21 is a high-availability central processing unit module, developed exclusively for the fault-tolerant Siemens SIMATIC S5-155H programmable logic controller system. Built on a robust bit-slice architecture with specialized redundancy link processing, this computing module operates in a dual-subunit frame configuration to deliver bumpless, hot-standby switchovers without stopping factory production.

1. Operating Voltage: 5V DC

2. Current Consumption: Between 2.2 A and 3.8 A

3. Operating Temperature: 0°C to +55°C (32°F to 131°F)

4. Storage Temperature: -40°C to +70°C (-40°F to 158°F)

〖Product Applications〗

² High-Availability (Fault-Tolerant) Systems: Deployed in pairs within the Siemens SIMATIC S5-155H chassis to prevent costly plant shutdowns through instantaneous, bumpless background switchover.

² Critical Manufacturing Plants: Runs automation scripts for high-risk industrial processes such as chemical reactors, power generation, and glass production lines where logic failure causes massive loss.

² Redundant Network Control Blocks: Manages distributed processing alongside a companion CPU 946 or 947R unit to provide synchronized load-balancing over industrial field networks.
