Welcome to your new project. Imagine what you can build here.

I want make a board that trigger a green and red LED with three wire, 0V, 24V and output of proximity switch. but i want output wire remain 0V when not connected.

This project involves designing a portable device that can inject a 1kHz sine wave signal into a 100V audio line to detect short circuits. The device should be compact (around the size of a smartphone) and include LED indicators to show the status: a green LED for normal operation and a red LED for short-circuit detection. The device will be powered either by a switching power supply or rechargeable batteries.
