Elevator Relay SR6B4024: Reliable Switching Core from Nanjing Zhuye Elevatorparts
In the intricate control system of elevators, the relay acts as a “precision switching node,” facilitating signal transmission and circuit control for core functions such as door operation, floor indication, and safety protection. Its reliability directly impacts elevator operation stability and passenger safety. The Elevator Relay SR6B4024, exclusively supplied by Nanjing Zhuye Elevatorparts, is engineered to meet the rigorous demands of modern elevator applications. Compliant with international standards such as IEC 61810 and EN 61810, this 24V DC relay boasts excellent compatibility with mainstream elevator brands including Schindler, OTIS, KONE, and domestic brands like Mitsubishi Elevator. Whether for new elevator installations or old system maintenance upgrades, the SR6B4024 delivers stable switching performance trusted by elevator professionals worldwide.
Nanjing Zhuye Elevatorparts has always adhered to a stringent quality control system, and the SR6B4024 elevator relay is a perfect embodiment of this commitment. Each unit undergoes comprehensive quality inspections before leaving the factory, including contact resistance measurement, insulation performance assessment, mechanical durability trials, and high-temperature operation tests. The relay features silver alloy contacts that minimize ablation and oxidation, ensuring stable current 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. With an operating temperature range of -25℃ to 60℃ and anti-vibration design, it performs reliably in harsh elevator machine room environments. The SR6B4024’s compact structure allows for easy installation in limited control cabinet space, optimizing layout efficiency.
Usage Guide for Elevator Relay SR6B4024
Proper installation, wiring, and operation are crucial to maximizing the performance and service life of the SR6B4024 elevator relay. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform these operations to avoid safety hazards or equipment damage. Improper operation may lead to relay failure, circuit malfunctions, or even elevator system shutdowns. Before installation, confirm that the relay’s rated voltage (24V DC), contact capacity, and pin configuration match the elevator control system’s specifications. For any doubts, refer to the product manual provided by Nanjing Zhuye Elevatorparts or consult our professional technical team.
1. Pre-Installation Preparation

Prepare necessary tools: torque wrench, screwdriver, multimeter, wire stripper, and anti-static gloves. Clean the relay installation area in the control cabinet to remove dust, debris, and oil stains, as these contaminants can affect electrical performance and cause short circuits. Inspect the RY611024 relay for external damage, loose pins, or stuck contacts. Do not use the product if any defects are found. Verify that the control circuit voltage matches the relay’s rated 24V DC to avoid coil burnout.
2. Installation & Wiring

Avoid installing it near heat sources, high-voltage components, or direct sunlight to prevent interference and overheating. Follow the wiring diagram from Nanjing Zhuye Elevatorparts strictly: connect the control signal wires to the relay’s coil terminals (usually marked as A1 and A2) and the load wires to the normally open/normally closed contact terminals. 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 control wires and power wires separated to reduce electromagnetic interference. After wiring, use a multimeter to check the insulation resistance between terminals and confirm the contact on-off status.
3. Debugging & Daily Maintenance
After completing installation and wiring, conduct a comprehensive debugging test. Energize the control circuit to check if the relay engages and disengages smoothly without abnormal noise. Use a multimeter to verify the on-off status of contacts under different control signals, ensuring accurate switching. Simulate various elevator operating scenarios (e.g., door opening/closing, floor arrival) to confirm the relay responds correctly. Incorporate the relay into the elevator’s regular maintenance plan, with monthly inspections at a minimum. Clean the relay surface and terminals regularly to remove accumulated dust and oxidation. Check the tightness of wiring connections quarterly and monitor the relay’s operating temperature—any abnormal heating (exceeding 55℃) indicates a potential issue that requires immediate attention.
Replacement Cycle of Elevator Relay SR6B4024
SR6B4024relaymaintenancerelaying2-10℃ to 5test The replacement cycle of the RY611024 elevator relay is determined by operating frequency, working environment, and maintenance conditions. Under normal operating circumstances—elevator runs 12-24 hours a day, relay switching ≤2000 times/day, and the control cabinet environment is dry, ventilated, and maintained at -10℃ to 50℃—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This recommendation is based on long-term field test data, taking into account factors such as contact wear, coil aging, and mechanical component fatigue.

High-frequency operation accelerates internal component aging, while harsh environments increase the risk of circuit board corrosion and short circuits. For low-usage elevators such as villa elevators and small office building elevators (daily operation time less than 8 hours, door cycles <500 times/day) in stable environments, the replacement cycle can be extended to 7-10 years. However, annual professional inspections by Nanjing Zhuye Elevatorparts’ technicians are mandatory to confirm parameter stability, output accuracy, and protection function effectiveness.
Immediately replace the SR6B4024 elevator relay if any of the following issues occur, regardless of service life: severe contact ablation, welding, or jamming leading to failure to switch; coil burnout, discoloration, or insulation damage causing failure to engage or frequent tripping; mechanical components are stuck, deformed, or damaged resulting in inflexible operation or abnormal noise; the relay produces continuous abnormal heating or sparks during operation; or frequent elevator control system malfunctions are confirmed to be caused by relay defects that cannot be resolved through maintenance. Timely replacement is critical to ensuring elevator operation safety and avoiding unexpected downtime.
