Siemens SITOP PSE200U 3 A NEC Class 2 Selectivity Module 4-Channel Input 24 V DC 6EP1961-2BA51
The Siemens SITOP PSE200U 3 A NEC Class 2 Selectivity Module 4-Channel Input 24 V DC 6EP1961-2BA51 is an advanced electronic power distribution and protection module designed for highly reliable 24 V DC industrial automation systems. Engineered by Siemens for maximum system availability, this selectivity module distributes power across four independent output channels while providing intelligent electronic protection against overload and short-circuit conditions. It is widely used in PLC control panels, SIMATIC automation systems, industrial machinery, and process control applications where uninterrupted operation and selective fault isolation are critical.
This module enhances system reliability by replacing conventional fuse-based protection with electronic monitoring technology. It ensures that only the affected channel is disconnected during a fault, while the remaining channels continue to operate without interruption. With NEC Class 2 compliant outputs and adjustable current thresholds, it is ideal for modern industrial environments requiring safe, efficient, and intelligent power distribution.
Key Features
4-channel electronic selectivity module for 24 V DC power distribution
NEC Class 2 compliant outputs for safe industrial applications
Adjustable current limiting from 0.5 A to 3 A per channel
Total input current handling up to 12 A for multi-load systems
Selective shutdown ensures only faulty channel is isolated
Integrated common signaling contact for fault indication
LED status indicators for real-time diagnostics per channel
DIN rail mounting for compact and easy control cabinet integration
