M5Stack StamPLC AC/DC Power Supply Module with Relay 12V 1A

The M5Stack StamPLC AC is an AC relay expansion module for the StamPLC controller, combining load control and system power supply in one unit. The module features a contact relay (normally open, single pole) with a switching capacity of up to AC 240V at 10A. The integrated AC-DC converter circuit with galvanic isolation supports input voltages from AC 100 to 240V and simultaneously supplies power for the relay load as well as a stepped-down DC 12V output for the main system. A programmable tri-color RGB LED indicates the operating status. The StamPLC controller communicates via the I2C protocol with an IO expansion chip for controlling relays and the RGB LED, saving IO resources. The module is suitable for industrial applications such as AC load switching and solenoid valve control. It can be mounted on DIN rails or by mounting holes. When using this module, no additional power sources other than DC 12V should be connected to the StamPLC.
