🔧 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 100–240V 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 🔩.
