Deep Report: Xh-m608 Manual

1. Introduction & Product Context

The identifier XH-M608 most commonly refers to a digital PID temperature controller module widely used in DIY electronics, industrial heating/cooling control, refrigeration, incubators, and 3D printer enclosures. It is part of a series of XH-Mxxx modules (e.g., XH-M601, M602, M609) sold through online marketplaces like Amazon, eBay, AliExpress, and Banggood.

Conclusion

U (Voltmeter Only): The relay does not function; it only displays the current voltage.

BAT+ / BAT-: Connect the battery you wish to monitor. This is where the module reads the voltage level.

Are you planning to use this for a solar setup or a DIY battery charger?

Save: The module saves automatically after a few seconds of inactivity. 💡 Practical Use Cases

P1 (Start Voltage): Sets the voltage at which the relay activates.

Safety Note from the Manual: The trigger terminals carry a low-voltage logic signal (5V). Do not apply mains voltage to these terminals.
