Eaton DILER-22-G Power Relay 24VDC XTRM10A22

Eaton DILER-22-G (XTRM10A22) Mini Power Control Relay | 24VDC Coil, 4-Pole (2NO + 2NC)

The Eaton Moeller® Series DILER-22-G(24VDC) (North American Catalog Designation: XTRM10A22TD / XTRM10A22) is a high-duty, 4-pole miniature industrial contactor relay engineered for demanding command, interlocking, sequencing, and pilot control circuits. Designed with an integrated DC economy coil circuit, the DILER-22-G draws minimal holding power (2.6 W pull-in / holding at 24VDC), allowing it to be actuated directly by 24VDC transistor PLC outputs, safety controllers, and marine automation I/O cards without an intermediate coupling interface.

Equipped with four positively driven contact sets (2 Normally Open + 2 Normally Closed), the relay guarantees mechanical anti-overlap according to IEC/EN 60947-5-1 Annex L. This design prevents simultaneous closure of NO and NC paths under abnormal operational or weld-fault conditions, making it suitable for hardware interlocks in marine engine control consoles, emergency trip matrices, power management systems (PMS), and harsh manufacturing environments subject to high mechanical vibration and temperature excursions.

Industrial & Marine Applications

• Marine Switchboards & Automation: Generator control panels, Power Management Systems (PMS), bilge and ballast valve actuation logic, main engine shutdown matrixes, and auxiliary boiler controls.
• PLC Digital Output Expansion: Galvanic isolation between sensitive microprocessor logic modules and field actuators, contactors, and solenoids.
• Safety Hardware Interlocking: Reversing starter control interlocks, star-delta transition delay circuits, and emergency stop monitoring circuits.
• Industrial HVAC & Refrigeration: Chiller sequencing, compressor safety chain relays, and draft fan interlocking.
• Conveyor & Material Handling Systems: Motor forward/reverse direction interlocking and limit switch status relays.

Frequently Asked Questions

What is the difference between Eaton DILER-22-G and XTRM10A22TD?

There is no functional or physical difference. DILER-22-G(24VDC) (Article No. 010042) is the global and European IEC part number from the Moeller series, whereas XTRM10A22TD (or XTRM10A22) is the North American catalog number for the exact same XT Series miniature control relay manufactured by Eaton.

Can I install top-mount auxiliary contact blocks on this 24VDC model?

Yes. The DILER-22-G base relay accepts standard front-mount auxiliary contact modules from the DILE series (e.g., 02DILE, 11DILE, 22DILE, 40DILE), allowing you to expand the unit up to an 8-pole control relay configuration.

What is the maximum wire gauge supported by the terminal clamps?

The screw clamps accept solid conductors from 0.75 mm² up to 2.5 mm² (AWG 18 to AWG 14) and flexible stranded conductors with bootlace ferrules from 0.75 mm² up to 1.5 mm². The recommended tightening torque is 1.2 Nm (10.6 lb-in).

Is this relay suitable for switching AC motor loads directly?

No. The DILER series is an auxiliary control relay designed for switching pilot circuits, contactor coils, and signal loads (AC-15 / DC-13 ratings). To switch 3-phase AC motor power directly, select the companion power mini-contactor DILEM-10-G(24VDC) or DILEM-01-G(24VDC) equipped with AC-3 rated main power poles.
