Elevator Contactor Auxiliary Contact DILM1000C-XHI11-SI: Reliable Accessory from Nanjing Zhuye Elevatorparts
In the intricate control system of elevators, the auxiliary contact of the contactor acts as a “signal transmission bridge,” coordinating the operation of various components such as door control systems, safety interlocks, and indicator lights. Its stable performance is crucial for ensuring the precise and safe operation of the entire elevator system. The Elevator Contactor Auxiliary Contact DILM1000C-XHI11-SI, exclusively supplied by Nanjing Zhuye Elevatorparts, is engineered to meet the rigorous demands of modern high-power elevator contactors. Compliant with international standards such as IEC/EN 60947 and UL 60947-4-1, this auxiliary contact features a 1NO+1NC (1 Normally Open + 1 Normally Closed) configuration, making it perfectly compatible with large-capacity contactors like the DILM1000 series. Whether for new elevator installations or maintenance replacements, it delivers consistent signal transmission performance trusted by elevator professionals worldwide.
Nanjing Zhuye Elevatorparts adheres to a stringent quality control system, and the DILM1000C-XHI11-SI auxiliary contact is a testament to this commitment. Each unit undergoes comprehensive testing, including contact resistance measurement, insulation performance assessment, mechanical durability trials, and arc resistance tests. The contact features high-quality silver alloy materials that minimize ablation and oxidation, ensuring stable signal transmission even under frequent switching conditions (up to 10 million operations). Its flame-retardant insulating shell meets EN 50274 protection standards, providing effective protection against accidental contact and arc hazards. With an operating temperature range of -25℃ to 60℃ and robust anti-vibration design, it performs reliably in harsh elevator machine room environments. The modular design allows for easy installation and replacement on matching contactors, reducing maintenance time and costs.

R on compatibility with specific contactor modelsProper installation, parameter setting, and operation are crucial to maximizing the protective performance of the DTA04DM24 temperature protection relay. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform these procedures to avoid safety hazards or equipment damage. Before installation, verify that the relay’s rated voltage (24V DC), temperature range, and interface match the elevator system’s specifications. Refer to the product manual provided by Nanjing Zhuye Elevatorparts or consult our technical team for clarification on parameter setting based on specific elevator models.

Confirm the control circuit voltage matches the relay’s rated 24V DC Confirm the coil voltage matches the control circuit requirements to avoid burnout.Begin by cutting off the elevator’s main power supply and control system power, then lock the power switch and place a “Maintenance in Progress” warning sign at the machine room and each elevator entrance to prevent accidental activation. Prepare essential tools: a torque wrench, screwdriver, multimeter, wire stripper, anti-static gloves, and a brush. Clean the installation area in the electrical control cabinet to remove dust, debris, and oil stains—contaminants can cause short circuits or poor contact. Inspect the relay boards for external damage, cracked substrates, loose components, or damaged interfaces; do not use defective products. Verify the control system’s voltage (usually 24V DC/110V AC) matches the boards’ rated voltage.
2. Installation & Wiring
Align the DILM1000C-XHI11-SI auxiliary contact with the mounting slot on the main contactor, ensuring the positioning pins fit securely into the corresponding holes. Press the auxiliary contact firmly until it clicks into place, confirming no looseness. Follow the wiring diagram from Nanjing Zhuye Elevatorparts strictly: connect the signal wires to the normally open (NO) and normally closed (NC) terminals of the auxiliary contact according to the control circuit requirements. The recommended tightening torque for terminal screws is 1.5-2.5 Nm, and the wire stripping length should be 8-10mm to avoid short circuits from exposed wire cores. Keep signal wires and power wires neatly separated to reduce electromagnetic interference, which is critical for stable signal transmission. After wiring, use a multimeter to check the on-off status of the NO and NC contacts to confirm correct wiring.
3. Debugging & Daily Operation
After completing installation and wiring, conduct a comprehensive debugging test. Restore power to the control system and activate the main contactor to check if the auxiliary contact switches synchronously—verify that the NO contact closes and the NC contact opens when the main contactor is energized, and vice versa. Simulate various elevator operating scenarios (e.g., door opening/closing, safety interlock triggering) to ensure the auxiliary contact transmits signals accurately to the corresponding components. During daily operation, incorporate the auxiliary contact into the elevator’s regular maintenance plan (recommended monthly inspection) as part of the contactor system. Check for loose connections, contact ablation, or abnormal heating regularly. Avoid using the auxiliary contact beyond its rated current (typically 6A) to prevent premature failure.
Replacement Cycle of Elevator Contactor Auxiliary Contact DILM1000C-XHI11-SI
The replacement cycle of the DILM1000C-XHI11-SI auxiliary contact depends on the operating frequency of the main contactor, working environment, and maintenance conditions. Under normal operating parameters—elevator runs 12-24 hours daily, main contactor switches ≤1000 times/day, and the machine room is dry, ventilated, and maintained at 0℃-40℃—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 2-4 years. This timeline is based on long-term field data, accounting for contact wear, spring fatigue, and insulation aging, which are the main factors affecting the performance of auxiliary contacts.
main -2contact4-6. However,signal transmission accuracyFor elevators in high-temperature environments (e.g., unconditioned machine rooms in tropical regions) or high-traffic areas (shopping malls, airports) with frequent temperature fluctuations, the replacement cycle should be shortened to 1.5-3 years. Harsh conditions accelerate probe aging and insulation damage, increasing the risk of protection failure. For low-usage elevators (villa elevators, small office buildings with daily operation <8 hours) in stable, temperature-controlled environments, the cycle can be extended to 5-7 years. However, annual professional calibration by Nanjing Zhuye’s technicians is mandatory to confirm temperature sensing accuracy (error ≤±1℃) and protection response performance meet safety standards.
Immediately replace the DILM1000C-XHI11-SI auxiliary contact if any of the following issues occur, regardless of service life: contact ablation, welding, or jamming leading to failure to switch synchronously with the main contactor; significant increase in contact resistance causing signal transmission failure or delay; insulation damage, cracks, or discoloration on the shell; abnormal heating or sparks during operation; or frequent elevator control system malfunctions (e.g., incorrect indicator lights, door control errors) caused by auxiliary contact defects that cannot be resolved through maintenance. Timely replacement is critical to ensuring the precise operation of the elevator control system and passenger safety.
