Industrial Automation 

Agricultural Equipment & Irrigation Systems 

Mining & Heavy Industry 

Industrial control relays are widely used in automation systems to manage signal transmission and equipment switching.

Typical applications include:
● PLC control panels and automation cabinets
● Conveyor and packaging line control
● Robotic systems and motion control
● Machine tool interlocking and safety circuits
● HVAC and building automation systems

👉 They ensure reliable signal isolation, circuit protection, and precise operation control in modern manufacturing lines.

Industrial relays play a key role in ensuring the stable operation of agricultural automation equipment.

Typical applications include:
● Smart irrigation and pump control systems
● Greenhouse environmental control (temperature, humidity, lighting)
● Grain drying and storage monitoring systems
● Fertilizer mixing and automatic feeding machines

👉 Relays provide stable control under outdoor and variable conditions, improving energy efficiency and equipment reliability.

In harsh and high-power environments, industrial control relays are essential for safety and process management.

Typical applications include:
● Conveyor belt and hoist control systems
● Ventilation and drainage equipment automation
● Power distribution and motor protection circuits
● Emergency stop and safety interlock systems

👉 They offer high current capacity, vibration resistance, and reliable performance even under dusty or humid conditions.

Selection Criteria

Core Considerations

RY-ELE Product Reference and Recommendations

Load Type and Current

Load characteristics (resistive, inductive, capacitive), rated current, inrush current

The load type (e.g., resistive, inductive, capacitive) must be evaluated. The 8-pin relay socket supports 10A current. When selecting a relay, ensure its contact capacity meets requirements with sufficient margin.

Coil Voltage

Voltage Matching of Control Circuits

Ensure that the coil voltage (e.g., 24 VDC/24 VAC) matches the control signal voltage.

Switching Speed and Frequency

Operational response speed, switching cycles per second

If your application requires high-frequency operations, consider solid-state relays (SSR), which typically switch faster than electromechanical relays.

Operating Environment

Temperature, humidity, vibration, dust, etc.

In harsh environments (such as those with severe vibration), consider using solid-state relays (SSR) as they have no moving mechanical parts and offer superior vibration resistance. In humid or dusty environments, pay attention to the protection rating.

Mounting Method and Space

DIN rail mounting, PCB mounting, socket mounting, etc.

RY-ELE offers DIN rail-mounted relay sockets that save space and facilitate installation. Its ultra-thin relays are also suitable for compact spaces.

Safety and Isolation

Electrical isolation, safety certification

Select products that provide effective electrical isolation between control circuits and load circuits. Prioritize products that have obtained relevant safety certifications (such as CE, UL, etc.).
