This BTT module automatically shuts off the power supply after printing, which saves energy and is environmentally friendly.
It also reduces the risk of the printer staying on after printing is finished.

BIGTREETECH Relay V1.2 is an update of the original (BIGTREETECH V1.0).
A small MCU has been added to make the module more controllable and stable. In addition, short circuit detection on the 5 V line has been integrated. The module immediately shuts down to prevent a short circuit from occurring.

Features:

• Input voltage 85V – 265V AC
• Logic voltage: 3.3V – 5V DC
• Supports resumption of printing after the printer has been turned off
• Detection of power outages
• Short-circuit detection
