Thought for a moment

I completed the pre-layout risk review and documented the proposed corrections here: Engineering Risk Review Before PCB Layout.
Main finding: the current Q1 reverse-polarity stage is unsafe because VGS can reach about 32 V, and SMCJ33A can clamp above the LM2596 40 V max input. I recommend replacing the front end with TPS26630RGER or LM74700QDDFRQ1 + MOSFET, and replacing LM2596 stages with 60 V bucks or industrial DC/DC modules.
No schematic/BOM changes were made yet, and PCB layout was not started. Approve Package A in the review file if you want me to apply the robust industrial corrections.

Apply Package A corrections to the schematic and BOM only.

I’ll apply Package A at schematic/BOM level only: replace the unsafe low-side Q1 stage with a robust high-side protection/eFuse front end, update the transient strategy, and swap/annotate the regulator solution toward 60 V-capable industrial parts. I’ll verify datasheet requirements and rerun ERC; no PCB layout work will be started.

Project Specification: 24V Industrial Power Distribution
Purpose
Industrial 24 VDC power input, protection, distribution, regulated 12 V and 5 V outputs, diagnostics, and selectable 0V-to-PE bonding.
Explicit exclusions
  • No USB-C power input.
  • No ESP32.
  • No SHTC3 or environmental sensors.
  • No consumer sensor-node features.
  • Schematic and BOM only; PCB layout is intentionally not started.
Electrical requirements
  • Input: 24 VDC nominal, 18-32 VDC operating range.
  • Input connector: pluggable terminal block, 5.08 mm preferred, pins VIN+_24V, VIN-_0V, PE/CHASSIS.
  • Protection: fuse/electronic protection, reverse polarity protection, industrial transient/TVS protection, EMI/LC filter, optional inrush limiting.
  • Outputs: protected 24 VDC pass-through >=3 A, regulated 12 VDC >=2 A, regulated 5 VDC >=3 A.
  • Diagnostics: VIN_24V_PRESENT, 24V_OUT_OK, 12V_OK, 5V_OK LEDs and open-drain outputs PWR_OK_24V, PWR_OK_12V, PWR_OK_5V.
  • Test points: TP_VIN, TP_24V_OUT, TP_12V, TP_5V, TP_0V, TP_PE.
  • Grounding: 0V/GND DC return, PE/CHASSIS connection point, selectable 0V-to-PE bonding by 0 ohm option, RC network option, or not fitted.
Component policy
Use real orderable components with MPNs for critical connectors, protection devices, regulators, and diagnostic active devices. Generic passives are allowed only for ordinary resistors and capacitors. Prefer -40 C to +85 C and common distributors.
Assumptions to be validated
  • Input source can supply total downstream load plus losses.
  • Outputs may be simultaneously loaded to rated minimum currents.
  • Diagnostic open-drain outputs are external pull-up compatible; default design will include protective series resistance and label external pull-up requirement unless an onboard diagnostic supply is selected.
  • Final EMC/surge levels and safety certification class are not specified and must be confirmed before layout/certification work.
