I finished the design for a high current FET module.
This uses an external supply hooked up to the terminal block in the middle of the board. The removable terminal block can be mounted for vertical entry of the wires or horizontally from the right or left.
The FETs are On Semiconductor NCV8403A rated at 42V and 15A. The terminal blocks are rated to 6A per terminal. The FETs have integrated diodes to protect them on inductive loads. There are 4 independent channels with LEDs to show the status of each channel.
This would be ideal for driving solenoids and valves.
I will be ordering a batch within the next few days, along with the other 2 recent designs.
