This is a relay controller for machines such as 3D printers. It has a pair of DRV8220 H-bridge drivers for controlling a bicolor LED in a push button switch (e.g. GQ19F-10E/RG/12/S) and a bistable DJ-H series relay from Panasonic. These relays are specifically made for dealing with high inrush currents such as from SMPSs and can take up to 400A for a short time.
It has two channels for "nodes", which are external devices that need to be shut down in a controlled manner.
