Low-Voltage DC Ceiling Sensing For 12V\/24V Lighting<\/h2>\n\n

The RZ038 12V\/24V model is the low-voltage DC version of the recessed ceiling PIR motion sensor switch, intended for projects using a constant-voltage 12 VDC or 24 VDC power supply.<\/p>\n\n

It keeps the same compact ceiling-mounted 360-degree sensing format while separating the DC product from the 100-265 VAC 5A and 10A RZ038 models.<\/p><\/div><\/div><\/div><\/div>

Coverage For Storage, Utility, And Low-Voltage Lighting Areas<\/h2>\n\n

The sensor uses ceiling-mounted PIR coverage with high\/low sensitivity adjustment, helping installers tune detection for rooms where people enter, move through, or work for short periods.<\/p>\n\n

Use it when the project calls for DC lighting control and the power supply, load, and wiring path match the 12 VDC or 24 VDC manual requirements.<\/p><\/div><\/div><\/div><\/div>

Features, Benefits, Specs<\/h2>\n\n

The RZ038 12V\/24V model combines low-voltage DC power, 360-degree PIR detection, and adjustable timing and Lux controls so buyers can confirm DC supply fit and coverage before ordering.<\/p><\/div><\/div>

Features & Benefits<\/h2>\n\n
  • 12V\/24V DC input:<\/strong> Works from a constant-voltage 12 VDC or 24 VDC supply, with the manual listing a 10-30 VDC input range.<\/li>\n\n
  • 10A max work current:<\/strong> The DC model is specified with a 10A max work current for compatible low-voltage loads.<\/li>\n\n
  • DC wiring path:<\/strong> The manual diagram separates Black to DC positive, White to DC negative, Red to Load positive, and Load negative back to DC negative.<\/li>\n\n
  • 360-degree PIR detection:<\/strong> Ceiling placement gives broad room coverage with an 8-12 m detection diameter when installed within the manual conditions.<\/li>\n\n
  • Adjustable time delay:<\/strong> Choose 15 s, 30 s, 1 min, 3 min, 5 min, 10 min, or 30 min to match the room traffic pattern.<\/li>\n\n
  • Selectable Lux threshold:<\/strong> Set Off, 15 Lux, 25 Lux, or 35 Lux to control whether motion can switch lights on when ambient light is present.<\/li><\/ul><\/div><\/div><\/div><\/div>

    FAQ<\/h2><\/div><\/div>

    Is the RZ038 12V\/24V model for AC line voltage?<\/h3><\/div><\/div>\n\n

    No. This model is for a constant-voltage DC power supply. Use the RZ038-5A or RZ038-10A models for 100-265 VAC line-voltage applications.<\/p><\/div><\/div><\/div><\/div>\n\n

    What DC voltage does it use?<\/h3><\/div><\/div>\n\n

    The manual lists 12 VDC \/ 24 VDC input with a 10-30 VDC input range.<\/p><\/div><\/div><\/div><\/div>\n\n

    How is the DC model wired?<\/h3><\/div><\/div>\n\n

    The manual diagram connects Black to 12V\/24VDC positive, White to 12V\/24VDC negative, Red to Load positive, and Load negative back to 12V\/24VDC negative.<\/p><\/div><\/div><\/div><\/div>\n\n

    What is the max work current?<\/h3><\/div><\/div>\n\n

    The RZ038 12V\/24V manual lists max work current as 10A. Confirm the load and power supply before installation.<\/p><\/div><\/div><\/div><\/div>\n\n

    Does it have the same time-delay and Lux settings as the AC models?<\/h3><\/div><\/div>\n\n

    Yes. The manual lists the same time-delay options and Lux threshold options for the DC model.<\/p><\/div><\/div><\/div><\/div>\n\n

    Where should this ceiling sensor be installed?<\/h3><\/div><\/div>\n\n

    The manual recommends a 2.5-3.5 m installation height and advises avoiding heat sources, forced air, ventilation systems, ceiling fans, and hanging light fixtures near the sensor.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
