Solid State Relays

The CPC1018NTR is a type of solid state relay (SSR) designed for industrial use. It is a compact and highly reliable SSR that is normally used for power switching applications.

Application Field

The CPC1018NTR is an ideal choice for process control applications such as temperature control in process automation or motor speed control, as well as lighting switching. Additionally, due to its strong switching capacity and low power consumption, the CPC1018NTR is well-suited for applications in harsh conditions where electric motors or heaters require frequent on/off operations.

Working Principle

A CPC1018NTR SSR works by allowing a low power input control signal to operate a higher power switching mechanism. This is done by using a bi-metallic element to close the contact between two electrical wires. When the control signal is applied, the electrical resistance of the bi-metallic element changes, which causes the two electrical wires to connect. This "bridging effect" then allows the higher power to pass from one wire to another. When the control signal is removed, the bi-metallic element returns to its initial state, breaking the connection between the two wires.

The advantage of using a SSR with a bi-metallic switching element is that the device does not have to be replaced or recalibrated as compared to a mechanical relay. As the switching element is made up of two dissimilar metals which can easily be repaired or replaced, the CPC1018NTR is very easy to maintain and can be operated over a large temperature range.

Conclusion

The CPC1018NTR is a versatile and reliable solid state relay that can be used in many different applications. Its low power consumption and strong switching capacity make it well-suited for industrial applications, while its bi-metallic element makes it easy to maintain and repair.
