StamPLC AC is an AC relay expansion module compatible with the StamPLC host.

It integrates AC load control + system power supply, simplifying wiring during application development .

Equipped with a contact-type relay (SPST normally open), supporting up to AC 240V @ 10A line switching

Built-in AC-DC isolated conversion circuit supports AC 100240V input, powering both the relay load and providing a stepped-down DC 12V output for the main system .

Includes a programmable tri-color RGB LED for working status indication .

The StamPLC controller communicates via I2C protocol using an IO expansion chip to control the relay and RGB LED, saving IO resources .

Ideal for industrial-level applications such as AC load switching and solenoid valve control .
