Bigtreetech relay module V1.2 automatic shutdown module for 3D printer parts.

• BIGTREETECH Relay Module V1.2 is an automatic shutdown module designed for 3D printer setups that need safer and smarter power control.
• It works as an interface between your printer mainboard and external high-current devices, helping you switch power to loads such as heated beds, fans, and lights.
• For users in India building reliable home printers or print-farm style setups, the BTT relay module provides an easy way to manage power distribution and automate shutdown routines after prints complete (when supported by firmware/workflow).
• The module is rated for up to 10A and uses an SPDT relay, it can control devices that draw more current than typical control-board outputs.
• This makes it useful when you want to isolate a higher-current circuit while still controlling it from the printer electronics. In practical terms, it can help you toggle auxiliary devices on/off during prints, or support automatic shutdown behavior when a print ends—reducing idle power usage and improving overall safety practices.

Package Include
