Difference between PNP and Relais Output?

The PR’s has relais outputs, Relay outputs use an electromagnetic coil to actuate a switching contact. When the control voltage is applied to the relay coil, it either closes or opens the switching contacts to control the load.

Whereas PNP transistor outputs are commonly used in control circuits to switch electrical loads, such as relays, LEDs, or motors.

They are e used to provide a positive voltage signal to turn on or control a connected load. When a positive voltage is applied to the base, the transistor becomes conductive, and the collector is connected to the emitter, allowing current to flow to the load.

The main difference is that PNP transistor outputs represent an electronic method for controlling loads, while relay outputs are electromechanical devices. The choice between them depends on the specific requirements of the application and design preferences.
