• Four changeover contacts provide simultaneous multi-circuit control
• Adjustable delay from 0.1 to 3 min for precise timing control
• Rated contact current 5A supports common control loads
• Switching capability up to 250V AC for versatile interfacing
• Plug-in terminals enable quick replacement and maintenance
• IP40 enclosure allows indoor panel mounting in protected locations
• Adjustable delay from 0.1 to 3 min for precise timing control
• Rated contact current 5A supports common control loads
• Switching capability up to 250V AC for versatile interfacing
• Plug-in terminals enable quick replacement and maintenance
• IP40 enclosure allows indoor panel mounting in protected locations
Applications
• Suitable for sequenced motor start–stop control in panels
• Ideal for timed valve or actuator control in process systems
