EATON 4-Pole Auxiliary Contact Block 31DILE, 3NO+1NC Positively Driven, Front Mount, for DILM7-DILM38 048912

When contactors control safety-critical circuits, you need reliable feedback that the main contacts have actually changed state. The EATON 31DILE auxiliary contact block provides positively driven contacts that mechanically guarantee the signal reflects the true position of the contactor, preventing dangerous mismatches in control and monitoring loops.

Who is it for

This 4-pole auxiliary contact block is built for panel builders, machine OEMs, and maintenance engineers who use EATON DILM7 to DILM38 contactors and require dependable status signaling for interlocks, PLC inputs, or safety relays. It is especially suited for applications where EN 60947-5-1 Annex L positively driven contacts are mandatory, such as elevator controls, presses, and conveyor systems.

Main features

• 4-pole configuration: 3 normally open (NO) + 1 normally closed (NC) contacts for versatile signal routing.
• Positively driven contacts per IEC/EN 60947-5-1 Annex L, ensuring no simultaneous closed state between NO and NC contacts.
• Front mounting onto compatible EATON DILM contactors without tools, saving installation time.
• Screw terminals accept a wide range of conductors for secure, maintenance-friendly wiring.
• Rated insulation voltage up to 690 V and impulse withstand 6 kV for robust performance in industrial environments.
• High electrical endurance: 1.3 million operations at AC-15, 230 V, 4 A.
• Compact design integrates seamlessly with the contactor, preserving panel space.

Tips

Always verify that the contactor is de-energized before mounting or wiring the auxiliary block. For safety circuits, ensure the entire chain—contactor, auxiliary contacts, and monitoring relay—meets the required control category. Use appropriate screwdrivers to tighten terminals to the specified torque to avoid loose connections.
