SKU:A160
























StamPLC AC is an AC relay expansion module compatible with the StamPLC host. The module integrates AC load control and entire system power supply functions, effectively simplifying power wiring during application development. It features a contact-type relay (single-pole single-throw - normally open), supporting up to AC 240V@10A line switching. It also includes a built-in AC-DC isolated conversion circuit supporting AC 100 ~ 240V input, capable of simultaneously powering the relay load and providing a stepped-down DC 12V output for the main system. A programmable tri-color RGB LED is available for working status indication. The StamPLC controller communicates via the I2C protocol using an IO expansion chip to control the relay and RGB LED, effectively saving IO resources. This module is ideal for industrial-level applications such as AC load switching and solenoid valve control.
