Suitable for

• Emergency stop button monitoring
• Safety gate and limit switch monitoring
• Industrial machinery and production line safety
• Automation systems requiring reliable circuit interruption

When it may not be suitable

This relay is not intended for applications requiring high-frequency switching or complex programmable logic control, as it is a dedicated safety monitoring device. It should not be used in environments that exceed its specified electrical ratings or environmental operating conditions.

Key specifications

• Contact configuration: 3 normally open (N/O) and 1 normally closed (N/C)
• Supply voltage: 24VDC or 230VAC
• Function: Safety circuit monitoring
• Application: Industrial automation and machinery safety

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The relay is typically mounted on a standard DIN rail within a control cabinet. Wiring must be connected to the appropriate terminals for the safety sensors and the output circuits that control the machine power. Ensure that the supply voltage matches the configuration used. After installation, perform a functional test to verify that the relay correctly interrupts the circuit when a safety trigger is activated.

What to consider before purchase

• Verify that the supply voltage (24VDC or 230VAC) matches your existing control system.
• Ensure the contact configuration (3 N/O, 1 N/C) meets your specific safety circuit requirements.
• Check the physical dimensions to ensure compatibility with your control cabinet layout.

Usage recommendations

Regularly inspect the relay and associated wiring for signs of wear or damage. Periodically test the safety function to ensure the relay continues to operate correctly within the safety system.
