Eaton DILER-22 Auxiliary Contactor, 2 NO + 2 NC, 110V AC

The Eaton DILER-22 auxiliary contactor is a high-performance switching device engineered for integration into control and signaling circuits. Designed for reliability and precision, this unit operates with a 110V AC coil and provides a versatile contact configuration of 2 normally open (NO) and 2 normally closed (NC) contacts. Its compact design allows for efficient space utilization in control panels, making it an essential component for maintaining stable and safe operation in complex electrical systems.

Advantages

This auxiliary contactor offers exceptional operational reliability, ensuring consistent performance in demanding industrial environments. The robust construction minimizes the risk of mechanical failure, while the standardized contact arrangement simplifies circuit design and maintenance. By providing clear switching states, it enhances the overall safety and monitoring capabilities of automated systems, contributing to reduced downtime and improved process efficiency.

Suitable for

• Industrial automation and control systems
• Signaling and monitoring circuits
• Electrical distribution panels
• Motor control center auxiliary functions

This device is not intended for switching high-power main circuits or heavy-duty motor loads directly. It is strictly designed for auxiliary control purposes and should not be used in applications exceeding its specified electrical ratings or in environments with extreme vibration or corrosive elements that fall outside the manufacturer's environmental specifications.

Key specifications

• Coil voltage: 110V AC
• Contact configuration: 2 NO (Normally Open) and 2 NC (Normally Closed)
• Device type: Auxiliary contactor
• Application: Control and signaling circuits

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is typically mounted on a standard DIN rail within an enclosure. Ensure that the control circuit voltage matches the 110V AC coil requirement before connecting the supply wires. Secure all terminal connections firmly to prevent overheating and ensure reliable signal transmission during operation.

What to consider before purchase

• Verify that your control circuit voltage is compatible with the 110V AC coil.
• Ensure the contact configuration (2 NO + 2 NC) meets your specific logic requirements.
• Check available space in your control cabinet for mounting.
• Confirm the environmental conditions of the installation site are within the rated limits.

For optimal longevity and performance, regularly inspect terminal connections for tightness and ensure the contactor is kept free from dust and moisture accumulation. Periodically test the switching function during scheduled maintenance intervals to verify the integrity of the control logic.
