Specification Brand : SENSATA/CRYDOM BulletPoint : 3Pcs Single Phase SSR 35mm DIN Rail Fixed Solid State Relay Clip Clamp w./ 6 Mounting Screws -B119 BulletPoint1 : This board has a single Signal pin (the white wire). Normally, the relay's COM pin is connected mechanically to the NC pin and the NO pin is disconnected. BulletPoint2 : When the Signal pin is pulled high, the relay switches and the internal switch changes so that the COM pin is mechanically connected to the NO pin and NC is then disconnected BulletPoint3 : When the relay is active, a red LED is lit, and about 50mA of current from the red power wire is used to keep the coil switched on. Note, if power is lost, the relay will go back 'open'. BulletPoint4 : The connects for the relay are the white tubular thing at the far end of the PCB. You can poke wire into the holes, they will automatically grip onto wire that is 24AWG to 18AWG. Once you poke the wire in, give it a light pull to verify its clamped. To release the wire, use a thin screwdriver or pen to press on the button on the top while pulling the wire out. BulletPoint5 : Sturdy and Stable: The solid-state relay module is housed within a flame-retardant casing, boasting an integrated structure that's resilient to vibrations and shocks, guaranteeing ConnectorType : Screw CurrentRating : 10 amps CurrentRating1 : 10 amps CurrentRating2 : 7 amps ExternallyAssignedProductIdentifier : 4783201186228 ExternallyAssignedProductIdentifier1 : 0759245422404 ExternallyAssignedProductIdentifier2 : 759245422404 ExternallyAssignedProductIdentifier3 : 00079458991475 ExternallyAssignedProductIdentifier4 : 079458991475 ItemName : SENSATA/CRYDOM - 84134020 - Solid State Relay, 50 A, 280 VAC, Panel, Screw, Zero Voltage Turn On ItemPackageDimensions_Height : 6.5024 centimeters ItemPackageDimensions_Length : 1.7018 centimeters ItemPackageDimensions_Width : 6.4008 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : solid-state-relays Manufacturer : Sensata Technologies/Crydom Material : Copper MaximumSwitchingCurrent : 10 amps MaximumSwitchingVoltage : 60 volts MeasurementSystem : Imperial MinimumSwitchingVoltage : 59 volts_of_direct_current ModelNumber : 84134020 MountingType : Panel Mount NumberOfItems : 1 OperationMode : Automatic PartNumber : 84134020K ProductDescription : CROUZET SSR GN IP00 SSR, 50A/2 ProductSiteLaunchDate : 2020-05-18T08:30:20.124Z SpecificationMet : En60947-5-1, En60204-1, Vde 0113-1 SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 27000000 Wattage : 1200 watts
