Acoustic control relays, or signal relays, are electronic components that convert acoustic input into electrical pulses. The G2A-432A AC200/220 is an example of such a signal relay that offers up to 2 amps of current capacity. These relays are particularly useful in industrial automation and audio applications.

In industrial settings, the G2A-432A AC200/220 is used to detect sound level changes, including acoustic signals that use a frequency range between 100 Hz and 20 kHz. With the relay connected to a circuit, the sound level will trigger a voltage or current response, controlling the application\'s output. This application requires a minimum operating voltage of 11 V AC (40 V DC maximum) and an input sound pressure level of up to 122 dB. The signal relay can detect sound from up to a maximum distance of 1.5 m, while its maximum power consumption levels are 3 VA at 0.8 W.

The G2A-432A AC200/220 works using a built-in microphone enclosed in a rugged plastic housing, which is designed to increase the components durability and soundproofing. The microphone can detect sounds that are within the accepted range and a circuit is triggered when the sound reaches a certain level. This allows an array of signals to turn on lighting, motors, start or shut down a process, and much more.

The G2A-432A AC200/220 signal relays also feature an adjustable sensitivity, so users can adjust the sound pressure level received to better control the output. This makes the G2A-432A AC200/220 ideal for applications such as sound level sensors, pushbutton switches, doorbells, and microphones. The G2A-432A AC200/220 has a long service life with a rated minimum insulation resistance of 1,000 MΩ, an electrical strength of 500 V AC, and a nominal contact blow of 6,000 VA.

The G2A-432A AC200/220 signal relays are designed to simplify wiring by providing a simple touch output with minimal power requirements. This allows it to be used in compact applications, such as automotive, medical, office automation, and audiovisual systems. With a wide range of sensitivity settings, the G2A-432A AC200/220 signal relays can be set to almost any desired level, making them an ideal choice for a variety of sound-sensitive applications.
