Alarm Lighting PATLITE LR4-302WJBU-RYG Fixed Amber Green Red LED

The PATLITE LR4-302WJBU-RYG Fixed Amber Green Red LED is a compact, three-color alarm lighting unit designed for 24V DC systems. Its slim profile and 40 mm width allow installation in constrained spaces while providing clear visual status indication using amber, green and red LEDs. The unit consumes up to 1.3W and is RoHS certified for compliance with environmental regulations, making it suitable for industrial and commercial signal applications.

Advantages

This fixed alarm lighting unit provides distinct, easily recognizable color signals (amber, green and red) in a single compact housing. Low power consumption ensures minimal impact on system power budgets, while the 24V DC operation aligns with common control and automation installations. The narrow 40 mm body simplifies mounting in panels, machinery frames, or wall brackets. RoHS certification indicates restricted hazardous substance compliance, supporting environmentally conscious installations.

Suitable for

• Machine status indication on production lines
• Panel-mounted visual alarms in control cabinets
• Visual signaling in automation and conveyor systems
• Equipment status display in laboratories and testing stations

Key specifications

• Light colors: amber, green, red (fixed)
• Operating voltage: 24 V DC
• Maximum power consumption: 1.3 W
• Body width: 40 mm
• Certification: RoHS compliant

How to use

Install the LED unit on a flat surface or within a panel opening sized to accommodate the 40 mm width and the unit's mounting features. Connect the 24 V DC power supply according to system wiring standards, ensuring polarity and any applicable protective elements such as fuses or overcurrent protection are in place. Use separate control outputs or wiring to switch each color as required for your signaling logic. Verify illumination and color distinction after installation and before commissioning.

Usage recommendations

Place the unit where it is visible from typical operator positions and avoid direct exposure to strong ambient light that could reduce color recognition. Use appropriate mounting hardware and secure wiring to prevent vibration-related loosening. Maintain periodic visual checks for LED functionality and clean the lens with a soft, dry cloth to preserve visibility.
