Eaton DILA-31 Auxiliary Contactor, 3NO + 1NC, 24V AC Coil

The Eaton DILA-31 auxiliary contactor is a high-performance switching component engineered for demanding control circuit applications. Designed to provide reliable signal management, this device features a configuration of 3 normally open (NO) and 1 normally closed (NC) contacts, powered by a 24V AC coil. Its robust construction ensures consistent performance in industrial automation environments, facilitating precise control and enhanced operational safety across a wide range of electrical installations.

Advantages

This auxiliary contactor stands out due to its compact design, which allows for efficient space utilization within control panels and electrical cabinets. The integration of 3NO and 1NC contacts provides versatile switching capabilities for complex logic circuits. Built to meet rigorous industrial standards, the Eaton DILA-31 offers long-term durability and resistance to mechanical wear, ensuring that control signals are transmitted accurately and reliably over extended periods of operation.

Suitable for

• Industrial automation and control systems
• Signal switching in electrical panels
• Interlocking and auxiliary control circuits
• Integration with motor starters and contactors

This device is not intended for switching high-power main circuits or heavy motor loads directly, as it is specifically designed for auxiliary control signals. It may also be unsuitable for environments where the control voltage differs from the specified 24V AC requirement without the use of additional transformers or converters.

Key specifications

• Contact configuration: 3 Normally Open (NO), 1 Normally Closed (NC)
• Coil voltage: 24V AC
• Application: Control circuit switching
• Design: Compact modular construction

To install the Eaton DILA-31, mount the device onto a standard DIN rail within your control cabinet. Ensure that the control circuit wiring is securely connected to the designated terminals according to the wiring diagram. Verify that the supply voltage matches the 24V AC coil rating before energizing the system to prevent damage to the internal components.

What to consider before purchase

• Verify that your control system operates on a 24V AC supply
• Ensure the contact configuration (3NO + 1NC) meets your specific logic requirements
• Check available space in your enclosure for mounting

For optimal performance and longevity, ensure that the contactor is installed in a clean, dry environment protected from excessive dust and moisture. Regularly inspect terminal connections to maintain secure contact and prevent signal interruptions.
