12vdc relay current specification selection and safety precautions

1. According to the nature of the load and the rated current, the maximum output current IT value of the 12vdc relay is selected as follows:
(1) Resistive load: The current specification of the 12vdc relay should be more than twice the rated current of the load.
(2) Inductive load: 12vdc relay current specification should be more than 3 times the rated current of the load.
(3) If the load current fluctuates greatly, the current multiple should be appropriately increased.
(4) Ensure that the actual working current of the load cannot exceed the nominal maximum output current of the 12vdc relay during the entire operation process.

2. Product application:
SSR series solid state relay adopts flame-retardant engineering plastic shell, epoxy resin potting, threaded terminal wiring, high structural strength, impact resistance, strong vibration resistance, small input drive current, and can be easily connected with computer terminals and various digital Program-controlled circuit interface is widely used in petrochemical equipment, food machinery, packaging machinery, textile machinery, CNC machine tools, plastic machinery, fitness equipment, entertainment facilities and other automation control fields.
It is especially suitable for harsh environments such as corrosion, humidity, dustproof, explosion-proof and other occasions, and occasions with frequent switching. It is a replacement product for AC contactors.
