DIN Mounts: Chinese 4 relay modules
thingiverse
These are DIN mounts for a couple of very common Chinese 4 relay modules: 1. Simple 4-Relay module (75 x 55 mm board size, 4 mounting holes) 2. LCTech ESP-01 4-channel serial relay module (63 x 60 mm board size, 2 mounting holes) I'm using these to control a set of high-voltage contactors from the Raspberry Pi sitting on the same DIN rail. Based on an excellent https://www.thingiverse.com/thing:2610621 design. FreeCAD files are included, please feel free to customize to your needs.
