CMRD6065-10 Application Field and Working Principle

Solid State Relays (SSRs) are a type of electronically controlled switch used in industrial applications. This article will discuss the application field and working principles of CMRD6065-10, a type of SSR.

Application Field

The CMRD6065-10 is a three-terminal solid state relay (SSR) suitable for controlling a wide range of loads up to 1.0A at either 24 or 48V DC. It is especially well-suited for use in controlling resistive loads, such as small motors, heating elements, and lamps due to its low switching noise and low on-state resistance. The CMRD6065-10 is also suitable for controlling more complex loads such as fan motors, pumps, and other inductive loads due to its fast response time and tight off-state current leakage protection.

Working Principle

The CMRD6065-10 comprises a latching opto-coupler and MOSFET in a single package. The opto-coupler is a light-activated electrical switch, which means that when exposed to a certain amount of light (in this case, Infra-red), it will switch on, and when the light is removed, it will switch off. When idle, the CMRD6065-10’s internal latching opto-coupler is closed regardless of any external electrical influence, which keeps the external MOSFET off. When a suitable external trigger signal is applied, the relay is closed until the trigger input is removed. The CMRD6065-10 is designed to maintain the closed state even in the absence of the trigger signal. The external MOSFET is also protected against excessive voltage or current due to its integrated protection circuit.

Conclusion

The CMRD6065-10 is a three terminal SSR suitable for controlling a wide range of loads up to 1.0A at either 24 or 48V DC. It is also suitable for controlling more complex loads such as fan motors, pumps, and other inductive loads due to its fast response time and tight off-state current leakage protection. The CMRD6065-10 comprises a latching opto-coupler and MOSFET in a single package. When exposed to a certain amount of light (in this case, Infra-red), it will switch on, and when the light is removed, it will switch off. The CMRD6065-10 is designed to maintain the closed state even in the absence of the trigger signal.
