Eaton DILA-40 contactor auxiliar, 24 V DC, 4 NA, conexiones por tornillo

Auxiliary contactor with four normally open contacts, engineered to reliably multiply a single 24 V DC control signal into four independent circuits. Its compact footprint and screw terminal connections make it a practical choice for space-constrained control cabinets.

Advantages

With four NO contacts, the DILA-40 eliminates the need for multiple interposing relays, simplifying wiring and reducing component count. The DC coil draws only 2.5 W in holding mode, minimising heat generation and lowering energy costs. Built for longevity, it achieves a mechanical life of 10 million operations and an electrical life of 1 million cycles under AC-15 load. IP20 terminal protection guards against accidental contact, while the 690 V insulation rating and 6 kV impulse withstand voltage ensure safe operation in industrial environments.

Suitable for

• Industrial automation systems requiring multiple interlocking and signalling contacts
• Switching auxiliary circuits in motor control centres and switchgear
• Extending the output capabilities of PLCs, timers, and sensors
• Controlling larger contactors and contactor assemblies
