IntroductionThis is a 4-channel optpcoupler-isolated relay Arduino UNO Shield, capable of controlling high-power devices operating at AC 240V 5A or DC 24V 5A for each channel.In a home automation project, relay modules play a crucial role in managing devices such as lights, pumps, garage doors, speakers, power outlets, and fans. However, traditional relay modules are burdened by space requirements, intricate wiring, and a potential for unreliable operation. Moreover, low-quality relay modules lacking optocoupler isolation compromise the safety of the entire project.By adopting the Arduino Shield approach, this product not only eliminates the need for complex wiring but also provides a substantial boost to project reliability. Through the integration of a 4-channel relay, it enables an Arduino UNO mainboard to exercise comprehensive control over a diverse range of devices.4 Channel Relay Shield for ArduinoFurthermore, this expansion board boasts an XBee interface in addition to 14 3-pin digital ports and 6 3-pin analog ports. With the inclusion of the XBee interface, users have the freedom to integrate wireless modules like Bluetooth, WiFi, or Zigbee, unlocking a realm of advanced capabilities such as IoT integration, seamless smart home integration, convenient mobile control, and efficient coordination among multiple devices.Arduino Uno Relay Shield Boasts an XBee InterfaceWith its 4-channel optocoupler isolation and independent power supply features, this relay expansion board effectively isolates the electrical connection between AC and DC, guaranteeing the utmost electrical safety. This meticulous design effectively eliminates any potential electromagnetic interference, thereby safeguarding the Arduino mainboard from the perils of high-voltage electrical signals and mitigating the risk of damage.FeaturesCompatible with Arduino UNO Rev3Each Relay has its own test button to test the connectionStandard DFRobot 3 Pin outXBee I/O direct controlSpecificationCompatible with Arduino UNO Rev34 buttons to test moduleLED status indicator of relaySupport Xbee IO directly controlXbee socket for wireless communicationSelectable digital IO pin for control (Default digital 2,7,8,10) 6 channels Analog IO & 13 channels Digital IO Up to 4 Relay with photo-coupled circuitContact Rating 3A AC 120V / DC 24VMax Switching Voltage AC 240V / DC 60V (Less than 38V is recommended)Max Switching Current 5AMax Switching Power AC 360VA / DC 90WElectrical Life (Min) 100,000 OperationsMechanical Life (Min) 10,000,000 OperationsSafety Standard(relay) UL cUL TUV CQCCoil Working Voltage 9VDCWorking temperature -30℃ to +85℃Working Humidity 40% - 85%Size: 95x65mmDocumentsWiki (Relay Shield for Arduino V2.1)SchematicsBoard LayoutSample codeHJR4102 datasheetShipping ListRelay Shield for Arduino V2.1 x1Nylon stand-off with screw x2
IntroductionArduino Opta, specially designed for PLC engineers, is a secure, easy-to-use micro PLC with industrial IoT capabilities.Opta is equipped with frequently used networks and protocols in multiple industries, and supports both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram). And its powerful STM32H747XI dual-core Cortex-M7 + M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications.Secure and durable by design, Opta supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 standard compliance. Meanwhile, it maintains Arduino Pro's signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches. Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with intuitive Arduino Cloud (or third-party services). Users can update wireless firmware and achieve remote control easily.Opta is mainly programmed on Arduino PLC IDE, which makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart, or Instruction List) and users can quickly code PLC applications or port existing ones to Arduino Opta.Integrate the micro PLC with users' existing machines, devices, and production lines, or combine it with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.Integrate the micro PLC with users' existing machines, devices, and production lines, or combine it with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.Arduino Opta is available in three variants:Arduino Opta Lite: onboard Ethernet and USB-C portsArduino Opta RS485: onboard Ethernet and USB-C ports, plus RS-485 connectivityArduino Opta WiFi: onboard Ethernet and USB-C ports, plus RS-485 and WiFi/Bluetooth LEApplicationsEnergy managementTank level monitoringUse as an RTUSpecificationSupply Voltage: 12-24VDCInput: Analog/digital input × 8Output: Relay × 4 - Normally Open (NO) - Maximum: 10A per relayProcessor: Dual-core ST STM32H747XI processorMemory: 1 MB RAM(Programming)Flash memory: 2 MBFlash QSPI: 16 MB Flash QSPIProgramming Languages: Arduino + IEC-61131-3 (LD-SFC-FBD-ST-IL)USB Connection: Used for host and device operations, programming/refresh, and power supply for programming (not for driving external high-power peripherals)Communication: support 10/100 Ethernet (TCP/IP or Modbus TCP) USB-C RS485 half duplexSecurity: ATECC608B secure elementIP Protection: IP20Operating Temperature: -20℃ to 50℃ (-4℉ to 122℉)Compatible with DIN railDocumentsProduct wikiDatasheetFull PinoutGetting Started with Opta™Shipping ListArduino Opta RS485 Micro PLC x1
