pcb - Circuit Board Design...Getting Rid Of A Relay and Adding a Choke and Capacitor Filter?

^{simulate this circuit – Schematic created using CircuitLab}

Figure 1. Original Schematic

Is there any way to get rid of the relay in this circuit?
And would it be wise to add in a power regulator? If so how?

Figure 2. Edited @Transistor's schematic

• Changed Transistors to PNP


• Changed Bottom Proxy to NO 2 wire proxy


• Changed Top Proxy to NO 2 wire proxy



• Added 2nd Digital Counter signal

If I did my research correct this should do the trick... Or is my research wrong.? @Transistor

Thanks
