Specification Brand : Adafruit 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 : Plug-In CurrentRating : 2 amps CurrentRating1 : 10 amps CurrentRating2 : 7 amps ExternallyAssignedProductIdentifier : 4783201186228 ExternallyAssignedProductIdentifier1 : 0749249328376 ExternallyAssignedProductIdentifier2 : 749249328376 ExternallyAssignedProductIdentifier3 : 00079458991475 ExternallyAssignedProductIdentifier4 : 079458991475 ItemName : Adafruit 4409 Stemma Non-Latching Mini Relay ItemPackageDimensions_Height : 6.5024 centimeters ItemPackageDimensions_Length : 1.7018 centimeters ItemPackageDimensions_Width : 6.4008 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : solid-state-relays Manufacturer : Adafruit Material : Copper MaximumSwitchingCurrent : 10 amps MaximumSwitchingVoltage : 250 volts MeasurementSystem : Imperial ModelNumber : 4409 MountingType : DIN Rail Mount NumberOfItems : 1 OperationMode : Automatic PartNumber : 4409 ProductDescription : STEMMA plug-and-play parts make your next project soldering-free! This is the STEMMA Non-Latching Mini Relay. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any microcontroller or microcomputer, with ease. No worrying about flyback diodes, level shifting, pin protection. The STEMMA board takes care of all that for you. You can use it with any 3V or 5V microcontroller/microcomputer. To use with a breadboard, Raspberry Pi or Arduino, pair with a JST 3-pin to breadboard cable. If you want to use with a Circuit Playground or micro:bit, we have a cable with alligator clips. 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. 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 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'. 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. You can switch up to 2A of resistive current at 30VDC or ~40VAC or lower. At 110VDC you can switch up to 0.3A, at 120VAC up to 0.5A, and at 250VAC you can switch up to 0.6A. Check the datasheet for the relay for the exact switching capacity, and of course, for reactive/inductive loads you will need to de-rate.
