Solid state relays are electronic switches with no moving parts, enabling them to surmount many of the challenges encountered in the operation of physical contact relays. The 84134080 solid state relay is a type of zero-crossing SSR that contains a field-effect transistor (FET) to open/close the switch contacts. This type of relay is particularly useful when used in applications that require frequent on/off cycles such as motor control and PLC timing applications.

The 84134080 SSR comprises of a sealed plastic case housing a trigger circuit, a logic element, a driver circuit as well as the gate-drive circuit. The trigger circuit is responsible for detecting switching conditions while the logic element provides the necessary circuitry for the switching operation. The driver circuit then transmits the signals to activate the FET. This FET is then responsible for controlling current flow through the contacts of the SSR.

The 84134080 SSR’s working principle is based on the concept of zero-crossing. This principle is defined as the phenomena in which the output current of the SSR follows a waveform that crosses when the input voltage reaches a specific reference voltage. During switching on and off, the SSR opens/closes the contact at the precise time when both the input and output voltage are equal, helping to reduce contact arcing, as no rolling contact gap exists.

The 84134080 SSR is designed to be used in a variety of applications such as motor control, signal transmission, and positioning control. The product is available in various current ratings from 2A to 16A at an operating voltage of 240V. In motor control applications, home appliances, and industrial automation, SSRs can be used to control motor speed and torque. In signal transmission, the SSRs can be used to switch in/out the signal sources, as well as for tone selection. The SSRs can also be used in positioning control applications such as in photoelectric sensors, light curtains, and safety shields.

The 84134080 SSR was specifically designed to provide high-interference immunity, low electromagnetic radiation, low power consumption, and an operating life of up to 100,000 cycles. The design also offers features such as overload protection, short circuit protection, and reverse polarity protection. Furthermore, the SSR has a built-in heat sink, allowing it to run for longer periods without risk of overheating.

In summary, the 84134080 solid state relay is a type of zero-crossing SSR used in a wide range of applications such as motor control, signal transmission, and positioning control. It uses the concept of zero-crossing to reduce contact arcing and comes with several protection features such as overload protection, short circuit protection, and reverse polarity protection. The product also has a long operating life of up to 100,000 cycles and requires low power consumption.
