DC SSR Design for 24V, 40A

I'm need a circuit designed, tested and gerber files for the following microcontroller based approach meeting performance specifications:

1. Scalable from 5-40A load current

2. AI/DSP for Fault Detection and Noise filtering

3. Optically isolated (5kV)

4. 3-32VDC trigger voltage (regulated on the input of the design)

5. 3-32VDC VCC input power (regulated in the input of the design)

6. Circuit timing based on load current (not AC line voltage).

7. RS422 / IEEE 4888 / RS 485 handshake for:

a. detected fault diagnostics

b. voltage / current monitoring

8. Power down (sleep) mode when not in use

9. 24VDC +/- 20% load voltage with 65 A current spikes

Attached is the PCB size/envelope.
