Specification Brand : Midzoo BulletPoint : 1 Channel 12V Thermistor Humidity Relay Humidity and Temperature Control Switch Relay Module ExternallyAssignedProductIdentifier : 4862440116842 ItemName : 1 Channel 12V Thermistor Humidity Relay Humidity and Temperature Control Switch Relay Module ItemTypeKeyword : humidifier-accessories Manufacturer : Midzoo Material : Copper PartNumber : MiMODULE-12342 ProductDescription : Product Descriptions: comes with genuine quality relay can directly control AC or DC loads, Normally open interface maximum load capacity: AC 0V--250V/10A DC 0V--30V/10A; 2. Temperature can be adjusted by potentiometer threshold, when the ambient temperature is above this threshold, relay, when the temperature falls below this threshold, the relay releases; 3. Design, smart regulation, when after the relay will automatically fine tune threshold, solves the problem of critical values over; 4. Module has a counter function, reverse polarity will not damage the power supply module; 5. Equipped with power indicator light (red), the relay status led (blue); 6. Operating voltage 12V; 7. With 4 fixing bolt holes for easy installation; 8. Module dimensions: 5.0CM*3.0CM*1.8cm; 9. Modules free with the 50cm fuse thermal sensor; Instructions: 1.Module ambient temperature-sensitive thermistor, typically used to detect changes in ambient temperature; 2.Module when the ambient temperature is higher than the set threshold, relay to pull-in, beginning public side and often connected (disconnected from the normally closed-end), when the outside temperature drops below a set threshold, the relay disconnect, and common Terminal disconnected from the beginning (with normally closed-end connected); 3.The common Terminal, normally open, normally closed three ports is equivalent to a double control switch, relay coil current, common Terminal and start turn-on, no power, common Terminal and the normally closed-end of conduction; Electrical parameters: Working voltage: DC 12V Operating current: relay after pull-in: 12V module is less than 50mA Before the relay actuation: less than 5mA Load capacity: AC 0V--250V/10A, DC 0V--30V/10A; temperature range - 20° to 100° Package included: 1PCS x 1 Channel DC 12V Thermistor Relay Sensor Temperature De ProductSiteLaunchDate : 2021-06-27T16:34:29.596Z
