Suitable for
Monitoring emergency stop buttons
Managing safety switches and interlocks
Industrial automation and control systems
Machine safety applications requiring 24V DC logic
This relay may not be suitable for applications requiring high-voltage switching directly through the safety contacts or for environments where the specific safety integrity level requirements exceed the device's certified capabilities. It is also not intended for use in non-safety-related general control tasks where a standard relay would be more cost-effective.
Key specifications
Supply voltage: 24V DC
Function: Safety relay for monitoring safety signals
Design: Compact housing for DIN rail mounting
Application: Emergency stop and safety switch monitoring
To use the Sick RLY3-EMSS100, mount the device securely onto a standard DIN rail within a protected control cabinet. Connect the safety-related input signals, such as emergency stop buttons or safety switches, to the designated input terminals according to the wiring diagram. Ensure the 24V DC power supply is correctly connected to the power terminals. Once installed, verify the system functionality by performing a safety test to ensure the relay correctly interrupts the output circuit when a safety signal is triggered.
What to consider before purchase
Verify that your system operates on a 24V DC power supply
Ensure the safety requirements of your machinery align with the relay's specifications
Check available space in your control cabinet for installation
