Siemens 6EP1961-2BA00 4-Channel Diagnosis Module, 24 V DC, 4x 10 A, 2–10 A Adjustable

Siemens 6EP1961-2BA00 SITOP select Diagnosis Module (4-Channel)

The Siemens 6EP1961-2BA00 SITOP select diagnosis module is a 4-channel electronic module for distributing and monitoring load current in 24 V DC control systems. It supports selective disconnection of an affected channel during overload or short-circuit conditions while maintaining power to remaining channels, depending on system wiring and protection design.

Selective Circuit Monitoring and Protection

• 24 V DC input (22–30 V DC operating range) with 40 A rated input current
• Four 24 V DC outputs, rated 10 A per channel
• Adjustable current response value per channel: 2–10 A (potentiometer)
• Blade-type fuse per output; delivered with 15 A fuses installed

Switch-off Behavior and Signaling

Per-channel switch-off behavior includes time-delayed shutdown near the set value and fast shutdown under higher overload conditions. The module provides per-channel LED status indication and a common signaling contact (NO) for external monitoring.

Applications

• Selective protection of PLC, I/O, sensor, and actuator branches in 24 V DC panels
• Load circuit monitoring with adjustable current thresholds
• DIN-rail control cabinet installations requiring compact 4-channel distribution
