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 . Features Integrated Power Supply & Control – Simplifies wiring for faster setup Contact-Type Relay – Reliable switching mechanism Built-in AC-DC Isolated Conversion – Supports AC 100–240V wide input range Programmable Tri-Color LED – Clear status indication I2C Protocol Control – Efficient communication, saves IO resources DIN Rail / Mounting Hole Installation – Flexible and secure mounting options Development Platforms – Compatible with Arduino & UiFlow2 Includes 1 x StamPLC AC 2 x Fixed connectors Applications AC/DC load ON/OFF control Solenoid valve control Remote control of industrial equipment Specifications Specification Parameter AC-DC Conversion Module Built-in AC-DC isolated conversion circuit (WCAL12-S12CA)Output power: DC 12V@1A (12W) Relay HF3FF/005-1HTF, 1-channel AC relay Insulation Resistance 100MΩ (DC 500V) Contact Rating Capacity: AC 240V@10ALifespan: ≥100,000 cycles (AC resistive load)Dielectric Strength: AC 1500V 1min Operate Time ≤10ms Release Time ≤5ms Interface Type 2 × 8P 2.54mm female/male header, KF128-2P 5.0mm Input Voltage AC 100 ~ 240V IO Expansion Chip PI4IOE5V6408 I2C@0x44 RGB LED 1 × NH-B2020RGBA-HF Installation Method DIN rail / mounting hole Product Size 80.5 x 50.5 x 27.1mm Product Weight 73.6g Package Size 82.0 x 60.0 x 28.0mm Gross Weight 80.9g Show more
