Safety Relays

• 3 safe, redundant relay contacts1 auxiliary contact (signaling contact)
• Connection of: Emergency stop buttons- Safety switches- Non-contact safety switches- OSSD-Outputs
• Single and dual-channel operation possible
• Feedback loop for monitoring downstream contactors or expansion modules
• Cyclical monitoring of the output contacts
• Indication of the switching state via LED

The emergency stop safety switching device SR3C is designed for safe isolation of safety circuits according to EN 60204-1 and can be used up to safety category 4, PL e according to EN ISO 13849-1.The internal logical system closes the safety contacts when the start button is pressed. If the safety switch is opened, the positively driven safety contacts are opened and safely switch the machine off. It is ensured that a single fault does not lead to a loss of the safety function and that every fault is detected by cyclical self-monitoring no later than when the system is switched off and switched on again.
