• Adjustable time delay from 0.5 to 60 seconds enhances flexibility
• Positive safety logic opens output contact on error detection
• User-friendly front panel for easy settings adjustment
• Visual indication through coloured LEDs signals operational status
• Designed to operate within -20°C to +60°C temperature range

Applications


• Ideal for monitoring voltage in control panels for pumps
• Utilised in wood-processing machinery and air conditioning systems
• Applicable in hoists and cranes for enhanced safety
• Perfect for escalators, ensuring consistent and safe operation

What happens if the voltage exceeds the rated threshold?


In cases of overvoltage, the relay will open its output contact, ensuring safety and preventing potential damage to connected equipment.

How do I adjust the time delay for the relay?


The time delay can be effortlessly adjusted using the front face selector, allowing settings between 0.5 seconds and 60 seconds according to operational needs.

Is there a memory function for voltage faults?


The relay can be configured to include a fault memory option, which retains the last detected fault until manually reset, providing essential information for troubleshooting.
