About this item

  • Solid State Relay (SSR)is industrial control appliance that uses power semiconductor devices for the main control part, compare with traditional magnetic contact industrial controllers, it is a higher-powered, intelligent, digital, systematic, and green development.
  • Wide input voltage range, small control current, samller or equal to 25mA;The photoelectric isolation between the input and output circuits, the insulation withstand voltage is 2500V.
  • Fast switching, zero-voltage turn-on, zero-current turn-off, low radio frequency interference;The built-in resistance-capacitance absorption protects the product from the impact of the instantaneous current.
  • The product is small in size, filled with epoxy resin inside, shock-proof, moisture-proof and corrosion-proof;No mechanical operation parts, long lifespan and high reliability.
  • When the output terminal and the load line are loosely connected, the product will be burnt due to the heat generated during power-on. The followings are the recommended screw installations for product wiring: M4 screw installation with a torque of 0.98~1.37N.m, M3 screw installation torque of 0.58~0.98 N.m, excessive torque will damage the relay.

Solid State Relay with Radiator

SSR Working:

The control inputs are connected internally to an LED, which shines across an air gap to light sensors.The light sensor is connected to the transistors which open or close, supplying the relay's load with power.When a transistor is closed, current can flow freely through the relay, causing the load and power supply to be connected. When a transistor is open, almost all current is blocked, causing the load to become disconnected from the power supply. The pairing of an LED with light sensors is called an optocoupler, and is a common technique to link two parts of a circuit without a direct electrical connection.

SSRs perform the same job as Mechanical Relays, but have the following advantages:

**SSRs produce less electromagnetic interference than mechanical relays during operation. This is mostly due to the absence of a phenomenon called contact arcing only present in mechanical relays, where the physical contacts of the relay tend to spark internally while switching. The reduced interference can also be attributed to the fact that SSRs do not use electromagnets to switch.

**The switch contacts of a mechanical relay will eventually wear down from arcing. An SSR will have a longer life because its internals are purely digital. Properly used, they will last for millions of cycles.

**SSRs turn on and off faster than mechanical relays (≈1ms compared to ≈10ms).

**SSRs are less susceptible to physical vibrations than mechanical relays.

**Since the switch inside an SSR isn't a mechanical switch, it does not suffer from contact bounce and operatessilently.
