### Key Features and Benefits
- 2 possible start behaviors: - Monitored manual start
- Safety level: PL e, SILCL 3
- Cross-fault and ground-fault monitoring to ensure line integrity
- 3 safe, redundant, diverse relay outputs for maximum safety
- 1 auxiliary contact (monitoring contact) for status monitoring
- Connection options: - Emergency stop buttons
- Force-guided relay contacts ensure that the safety function is maintained even if a fault occurs in the device.
- Cyclic monitoring of relay outputs to detect contact welding or failures.
- Feedback loop to monitor downstream contactors or expansion modules.
- LED display of switch status for quick diagnosis and maintenance.
- Automatic start

### Functionality and Safety Concept
The SR3D ensures safe separation of safety circuits according to EN 60204-1 and fulfills the stop function requirements up to PL e / SIL 3 according to EN ISO 13849-1 and IEC 61508. If the emergency stop circuit is activated (e.g., by pressing an emergency stop button or opening a safety door), the SR3D immediately interrupts the enabling current paths and stops the machine.
