The PS7342L-1A-E3-A is a three-terminal solid state relay (SSR) that is designed for switching low voltage and moderate current loads. It is ideal for motor-control, light dimming, lamp and audio/visual switching applications. The PS7342L-1A-E3-A is part of III Tyco Electronics’ Solid State Relays (SSRs) family, their smallest range of optically isolated SSRs.

Working Principle

The PS7342L-1A-E3-A is composed of an input control circuit and an output switch circuit. The input consists of two semiconductor elements, a photodiode attached to a gallium arsenide infrared emitter. The photodiode receives an incoming electrical signal and triggers an optical response. This optical response is then converted to a voltage drop and activates the output switching circuit. The output circuit is composed of an insulated-gate FET, which is connected to the load. When the voltage drop is sufficient enough, the FET conducts the current to the load. When the voltage falls below the specified value, the FET will switch off and disconnect the load from the power source. This switching off process happens instantly, ensuring that the power to the load is not disrupted.
