Solid State Relays

Introduction

A solid state relay (SSR) is an electronic switch that is driven by an input signal to turn an output signal ON or OFF. It is used in a variety of applications such as industrial automation, medical, telecommunications, automotive, and household appliances. Typically, solid state relays (SSRs) are designed to switch small DC loads as well as AC loads in the range of 2A to 10A.

PBB190 Application Field and Working Principle

The PBB190 solid state relay (SSR) is a single-channel SSR with a single input and a single output. It can be used to control a wide range of power devices such as motors, pumps, and heating elements. The PBB190 is designed to be easily integrated into existing control circuits and is suitable for both DC and AC loads.The PBB190 SSR operates in a standard zero-crossing (i.e., resistive) mode. This means that the relay will turn on the output when the input voltage reaches a certain threshold, and it will then turn off the output when the input voltage returns to a certain threshold. This type of operation eliminates the possibility of large inrush currents or arcing on the relay contacts. The input voltage can be either a low-voltage DC signal or an AC signal with a frequency of 50-60 Hz.The PBB190 also incorporates a neat feature called the Auto Reset Function. When the relay is in the OFF position, this feature will automatically reset the input signal when the input voltage returns to the specified threshold. This feature is useful in applications where the output is being disabled due to a fault condition or other event.The PBB190 has a rated input voltage range of 3-30V DC and 5-48V AC, and a rated output voltage range of 0-30V DC and 0- 500V AC. The PBB190 also has a maximum switching current of 7.5A. The PBB190 can be used in a variety of applications such as remote control systems, motor control, HVAC systems, and more. It also has a comprehensive set of safety features such as a built-in overload protection circuit, reverse polarity protection circuit, and over-temperature protection.

Conclusion

The PBB190 solid state relay (SSR) is a reliable and cost-effective solution for controlling the power of a variety of devices. It is suitable for both DC and AC loads, and has a maximum switching current of 7.5A. The PBB190 also features a convenient Auto Reset Function, as well as a set of safety features for added protection.
