Solid state relays (SSRs) are devices that allow for controlling of high power electrical loads, typically found in industrial applications. SSRs provide reliability and flexibly in controlling both low-power and medium-high power currents. The ED24C3R solid state relay is a popular choice for applications within industrial power control, automation and sensing.

ED24C3R Application Field

The ED24C3R solid state relay provides many advantages over other types of relays, making it a popular choice for industrial applications. It offers an exceptionally long service life with an estimated average of 50,000 operations, making it ideal for many small to medium duty applications and boasting a significant reduction in maintenance costs. It also provides a wide operating range (-40°C to +105°C) and is configured to operate from either 5 or 24 Volts DC.

The ED24C3R array is designed for the control of AC or DC current up to 25 Amp at 380 Volts and comes with LED indication for immediate feedback. Typical applications for the ED24C3R include motor control, solenoid, process control, light controls, heating, and fan control. It is also well suited for the majority of domestic and commercial projects.

ED24C3R Working Principle

The ED24C3R relay works by using an integrated solid state switch and a power supply. The relay controls high current loads with the use of a low power electronic signal. The signal can come from a variety of sources, such as a microprocessor, computer, or programmable logic controller. The signal is sent to the control circuits on the relay, which then activate a set of semiconductor components to open or close the switch.

When activated, the ED24C3R relay will open or close the circuit. This allows current to flow to or from the load, which in turn will result in the desired action. This is possible due to the extended power range of a solid state switch, which can operate from very low currents (~5mA) to very high currents (~25A).

Since no power is required to keep the switch on, the ED24C3R helps reduce the energy wastage associated with traditional relays, making it an excellent choice for environmentally conscious applications.

Conclusion

The ED24C3R solid state relay provides excellent performance for controlling high current loads in a wide range of industrial applications. It requires minimal maintenance and boasts an increased service life compared to traditional relays, helping to reduce energy wastage and cost. Thanks to its solid state switch, the ED24C3R is able to open/close a circuit from very low to very high currents, allowing for efficient and powerful operation.
