Specification Brand : waveshare BulletPoint1 : Configurable device address (1~255), multi devices can be cascaded on RS485 bus BulletPoint10 : High quality relay, contact rating: ≤10A 250VAC/30VDC. Rail-mounted ABS plastic enclosure, easy to install, safe to use. Multiple LEDs for indicating the MCU status and signal transceiving status BulletPoint2 : Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically BulletPoint3 : Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal BulletPoint4 : Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption BulletPoint5 : Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic BulletPoint6 : Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit BulletPoint7 : Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability BulletPoint8 : Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control BulletPoint9 : Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection Color : E22-400MBL-01 ConnectorType : Screw CurrentRating : 2 amps ExternallyAssignedProductIdentifier : 4034106033699 ExternallyAssignedProductIdentifier1 : 0739665087841 ExternallyAssignedProductIdentifier2 : 739665087841 IncludedComponents : Modbus RTU Relay (D) x1 Screwdriver x1 IncludedComponents1 : Modbus RTU IO 8CH x1 IncludedComponents2 : Power supply terminal adapter x1 IncludedComponents3 : Screwdriver x1 InputVoltage : 20 volts ItemName : Waveshare Industrial Modbus RTU 8-Ch Relay Module (D) with Digital Input and RS485 Interface, Multi Isolation Protection Circuits, 7~36V Power Supply ItemPackageDimensions_Height : 20.5994 centimeters ItemPackageDimensions_Length : 5.4102 centimeters ItemPackageDimensions_Width : 15.0114 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : io-modules Manufacturer : Waveshare Material : Plastic Material1 : Steel Material2 : Fiberglass MaximumSwitchingCurrent : 10 amps MeasurementSystem : Inch MinimumSwitchingVoltage : 7 volts_of_direct_current ModelName : Modbus RTU IO 8CH ModelNumber : Modbus RTU Relay (D) MountingType : DIN Rail Mount MountingType1 : Panel Mount MountingType2 : din_rail NumberOfBoxes : 1 NumberOfContacts : 3 NumberOfItems : 1 OperatingVoltage : 20 volts OperationMode : Automatic PackageLevel : unit PartNumber : Modbus RTU Relay (D) ProcessorCount : 1 ProductDescription : Used to test Ebyte's E22-400M22S Backup USB interface,can be directly plugged into the computer for use Pre-welded E22-400M22S All pins of the E22-400M22S module have been led out Stable and easy to develop Development kit embedded in the main control MCU:STM8L151G4 ProductSiteLaunchDate : 2024-01-05T06:43:17.431Z SpecificationMet : Modbus Rtu Relay (D) SupplierDeclaredDgHzRegulation : unknown SupplierDeclaredHasProductIdentifierExemption : 1 UnspscCode : 39122300 Voltage : 21 volts WarrantyDescription : 1 WirelessCommStandard : 802_11_B
