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
• Confirm compatibility with your existing safety sensors and switches

Always ensure that the installation and configuration of the safety relay are performed by qualified personnel in accordance with local safety regulations and the manufacturer's technical documentation to maintain the integrity of the safety system.
