SSR series of solid-state relay using flame-retardant engineering plastic shell, epoxy potting, thread lead-out wiring, with high structural strength, impact resistance, anti-vibration, the input drive current is small and convenient computer terminals and various digital Programmable circuit interface, widely used in petrochemical equipment, food machinery, packaging machinery, textile machinery, CNC machine tools, plastic machinery, fitness equipment, entertainment facilities, and other areas of automation and control. Particularly applicable to corrosion, moisture, dust, explosion-proof requirements such as harsh environments, and frequent switching occasions, AC contactor update replacement products.

 

Precautions

 

1. Do not load short circuit, so as not to burn solid state relays, optional special fast fuse;

 

2. Installation should be away from the heat source, more than one relay should be left between the full gap, the radiator temperature should not exceed 75 Temperature, should be away from electromagnetic interference, radio frequency interference and other strong sources of interference;

 

3. Heat the radiator, the contact surface should be in close contact, and coated with thermal grease to reduce the thermal resistance and improve the cooling effect;

 

4. Solid state relay output is off, there is still a certain leakage current output, in the use or design, please note;

 

5. Long-term working current should not exceed 70% of the nominal value Inductive load is best applied with varistor protection.
