Signal relays are electomechanical devices that use an input signal to control the switching of a circuit. The G6A-474P-ST20-US-DC24 is a 24V DC signal relay from OMRON with current ratings up to 2A. It is designed for a wide range of applications, especially those that require fast switching, small size and a long life.

Design and Construction

The G6A-474P-ST20-US-DC24 is a non-latching, single-pole, single-throw (SPST) signal relay. It features a compact design with low profile and reduced mounting height. The dimensions are 31.75 x 22.5 x 25mm (H x W x D). The relay is constructed of a molded plastic case with metal contacts and an epoxy sealed coil. It uses a UL94V-0 rated plastic dielectric material and can withstand a dielectric strength of between 500 and 1000V.

The G6A-474P-ST20-US-DC24 is configured with a high-quality, low-noise contact arrangement that provides reliable switching performance and long life. The contacts are gold-plated, silver-plated copper, with a minimum contact life of 50,000 cycles. The contacts can provide a maximum switching current of up to 2A and a maximum switching voltage of 300VAC/30VDC.

Specifications and Features

The G6A-474P-ST20-US-DC24 features a wide range of specifications in order to meet different application needs. It is rated for a operating temperature range of -22°F to 185°F (-30°C to 85°C), and a storage temperature range of -40°F to 257°F (-40° to 125°C). The G6A-474P-ST20-US-DC24 has a 12ms to 36ms contact operation time, and an 85ms to 240ms release time. The contact resistance is 0-50 milliohms, and the insulation resistance is greater than 100 megohms. It is also vibration-resistant, with a maximum rms acceleration of 1.82G and an operating frequency of 50/60 Hz.

Working Principle

The G6A-474P-ST20-US-DC24 works on a simple principle of electromechanical switching. A low power input voltage is applied to the coil, which creates an electromagnetic field. When the voltage is removed, the magnetic flux collapses and causes the switch contacts to close or open depending on the polarity of the voltage. The relay is designed with an internal coil current limiter which prevents the relay from overloading and burning out.

The G6A-474P-ST20-US-DC24 is an excellent signal relay for a wide range of applications due to its features and specifications. It provides reliable and long-life switching performance, and its compact design makes it an excellent option for many applications. It is an ideal solution for controlling the switching of various low to medium power circuits.
