Model XYWJ01 — DC12V LED Digital Time Delay Relay Module for reliable, programmable timing and cycle control. This compact, enclosed timer relay lets you automate lowvoltage DC circuits with precision and repeatable timing, reducing manual intervention and protecting equipment from unwanted start/stop cycles. Key benefits Precise, repeatable timing: digital LED readout and programmable settings give consistent delay and cycle control so processes run exactly when you want them to. Simplifies automation: replaces manual switches and improvised timing solutions to reduce human error and improve system reliability. Protects equipment and saves time: automatic delayed starts, timed shutoffs, and programmable cycles prevent frequent on/off stress and avoid unnecessary runtime. Enclosed module for safer installation: the module ships with a protective case to help prevent accidental contact and simplify mounting in project enclosures. Main features and attributes Model: XYWJ01 Operating voltage: DC 12V Display: LED digital display for clear timing and status readout Functionality: programmable time delay relay with trigger and cycle timing modes Outputs: relay control output suitable for switching DC circuits (module provides relay switching for controlled loads) Form factor: compact module supplied with a protective case for cleaner installation and basic environmental protection Performance: designed for stable timing operation at the specified DC12V supply Compatibility and installation notes Designed for use with 12V DC systems and lowvoltage electronic circuits. Connect the module to a stable DC12V supply and wire the relay output to the load you intend to control. The LED display and control interface let you program delay and cycle parameters before operation. For safe and reliable operation, confirm supply polarity and ensure wiring and load requirements match the relay's switching capability. Practical use cases Lighting delay and automation: set porch, display, or accent lighting to turn on or off after a preset delay or to operate in timed cycles, reducing manual switching. Motor or pump sequencing: add a controlled start delay or timed run cycle to small DC pumps or motors in hobby, irrigation, or small machinery applications to prevent inrush problems and reduce wear. Security and alarm control: use timed outputs to control sirens, strobe lights, or latch/unlatch circuits in alarm and access control systems where brief or repeated activation is required. Why choose XYWJ01 Combines a clear LED interface with programmable timing modes and a protective case to make installation and operation straightforward. Focused on DC12V applications where compact, repeatable timing control and relay switching are needed. A practical choice for hobbyists, technicians, and system integrators who need a dependable programmable timer relay without extra bulk. Basic precautions Use only with a regulated DC12V supply. Verify that the relay switching capacity matches your load before connecting heavy devices. Install the module in a dry, ventilated location and secure the protective case to reduce exposure to dust and accidental contact.
