Solid State Relays (SSRs) are a type of relay which is triggered by an external electrical signal, allowing power to be switched between two or more circuits, or between different levels. The RN2A48A50 is a single-pole, double-throw solid state relay which is used to control the flow of a large amount of power in an application. It is used in various applications, such as industrial automation, lighting control, motor control, and HVAC control.

Application Fields of the RN2A48A50

The RN2A48A50 is typically used in applications where exceptionally high power switching is required, such as in the operation of large motors, pumps, compressors, conveyors, heaters, and other high-power loads. This unit can also be used in the control of equipment operating from any single-phase line, such as resistive, stepper, and AC induction motors. It can also be used to control the switching of multiple outputs, such as multiple motorized valves or actuators. Its features make it suitable for use in applications where long-term reliability and safety are essential.

Working Principle of the RN2A48A50

The RN2A48A50 is designed to switch up to 48A at 50VAC. This unit consists of a silicon MOSFET which is triggered by an input voltage of between 4-32VDC. The MOSFET is then electrically isolated, by means of an optically isolated system, from the AC load. The isolated DC voltage is then sent to the control circuitry, which is then used to drive the relay. When the DC voltage is applied, the MOSFET will turn on, allowing power to be switched from the AC load.

When the AC load is turned off, the input voltage will rapidly drop, which will cause the MOSFET to cut off power to the load. The opto-isolated system in the RN2A48A50 is designed to prevent any feedback current from the AC load to the control circuitry. This is an important feature, as it ensures that the relay will remain safe and secure even when the power is switched off.
