Solid State Relays
Solid state relays, also known as SSRs, are an electronic switching device which have no moving parts,use a low power input signal to switch a higher power output.They control electrical circuits without the need for physical contact, making them a reliable and cost-effective alternative to switches and electromechanical relays.One particular type of solid state relay is the GNR20ACZ,which is typically used in automation and control circuits.
GNR20ACZ Application Field and Working Principle
The GNR20ACZ is an AC switching SSR, and is capable of switching loads from 5A to 20A at 250VDC and 280VAC.Its onboard LED indicates when the circuit is in an open or closed state,while minimized electromagnetic interference, overvoltage protection, and an internal photocoupler make this relay an ideal choice for automation and instrumentation applications.
The GNR20ACZ works in a manner similar to standard mechanical relays, with the input signal controlling the state of the output circuit.The relay is activated when an AC or DC signal is applied to the control terminal. This causes the relay\'s integrated optical coupler to turn on, low-power current passes through the coupler and energizes the SSR, and the AC or DC load is switched on. The relay\'s output remains switched on until the current supplying the control terminal is removed.
The GNR20ACZ also features a unique, built-in overvoltage protection, which prevents the SSR from automatically switching on in the event of a voltage surge or short circuit.This protection ensures that the relay remains safely operational during times when the input voltage exceeds the rated voltage of the relay, protecting both the relay and the downstream AC or DC load from potential damage.
In summary, the GNR20ACZ is an AC switching solid state relay which can be used to switch loads from 5A to 20A at 250VDC and 280VAC. With its low power input signal and high power output capability, overvoltage protection, and LED status indicators, the GNR20ACZ is the ideal choice for automation and instrumentation applications.
