Suitable for

• Industrial automation and control systems
• Signal processing circuits
• Electrical switchgear assemblies
• Motor control center monitoring

This device may not be suitable for high-power switching applications, as it is specifically designed for auxiliary control signals rather than primary power distribution. It is also not intended for use in environments exceeding its specified voltage or temperature ratings.

Key specifications

• Coil voltage: 110V AC
• Contact configuration: 3 NO (Normally Open) + 1 NC (Normally Closed)
• Device type: Auxiliary contactor
• Application: Industrial control circuits

How to use

The Eaton DILER-31 is designed for mounting within standard electrical control cabinets, typically on a DIN rail. Ensure that the control circuit voltage matches the 110V AC coil requirement before installation. Connect the control wiring to the designated terminals, ensuring all connections are secure and compliant with local electrical standards. Once installed, the device operates automatically based on the energization of the coil, triggering the state change of the auxiliary contacts to perform the intended control function.

What to consider before purchase

• Verify that your control circuit voltage is compatible with the 110V AC coil.
• Ensure the contact configuration (3 NO + 1 NC) meets your specific logic requirements.
• Check available space in your control panel for mounting.
• Confirm environmental conditions are within the manufacturer's specified operating range.

Usage recommendations

For optimal performance and longevity, ensure that the contactor is protected from excessive dust, moisture, and extreme vibrations. Regularly inspect terminal connections for tightness and verify that the coil voltage remains stable during operation to prevent premature wear.
