The 630V Relay Module Switch Trigger Time Delay Circuit Timer Cycle Adjustable (model 828) is a compact control module that combines a relay with a programmable delay and cycle timer. It is designed to be triggered by a switch input and powered from a 630V supply, enabling precise, automated switching of connected loads. This module is suitable for DIY projects, prototyping, and small automation tasks where timed relay control is required. Key benefits Enables automated control by delaying the relay turnon or turnoff according to a set schedule. Adjustable timing provides flexibility for different tasks without hardware changes. Simple switchtrigger input with relay output to drive loads directly. Compact form factor suitable for integration into control panels, enclosures, or breadboards. Wide supply voltage range for easy integration with common power sources and control signals. Key attributes Functionality: Relay module with time delay circuit and adjustable timer; cycle adjustable. Compatibility: Power supply range 630V; designed for switchtrigger inputs and relaydriven loads. Size: Dimensions not specified in the listing. Material: Material not specified in the listing. Performance: Provides adjustable delay and cycle timing for reliable, programmable relay control. Two to three use cases Delayon lighting control: Use a door or motion sensor as the trigger, and have the light turn on after a userdefined delay to avoid short or false activations. Cycled actuator or indicator: Drive a small motor, solenoid, or LED indicator with a repeatable on/off cycle for signaling, vending, or automated processes. Simple sequencing in small automation: Create timed sequences where one device activates after a programmable delay following a trigger, then repeats on a defined cycle. Setup and use Connect a 630V power supply to the module. Provide the trigger signal via the switch input. Connect the load to the relay output. Adjust the delay setting to your required time and set the cycle timing for repeated operation as needed.
