Technical Specifications

Key Features and Benefits The STP301-4-0ER-0 offers several distinctive features that make it an excellent choice for industrial visual indication applications. Its four high-intensity LEDs provide clear and visible signaling even in well-lit environments, ensuring operators can monitor system status from a distance. The multi-color LED configuration allows for versatile status representation, with red indicating alarms, green for normal operation, yellow for warnings, and blue for informational messages, thereby reducing the need for multiple indicator modules. The module’s low current consumption of 20mA per LED makes it energy-efficient, reducing operational costs over time while minimizing heat generation. The IP65 protection rating ensures the STP301-4-0ER-0 is dust-tight and protected against water jets, making it suitable for deployment in challenging industrial settings where exposure to moisture and dust is common. The compact dimensions of 80mm x 40mm x 20mm and lightweight design of 0.15kg allow for flexible installation in control panels with space constraints. The dual mounting options of panel mounting and optional Din Rail provide further installation flexibility, adapting to different cabinet layouts and user preferences. The STP301-4-0ER-0 also demonstrates exceptional reliability with an expected LED lifespan of over 50,000 hours, significantly reducing maintenance frequency and associated costs. These features collectively translate into substantial benefits, including improved operator response times due to intuitive visual feedback, enhanced system safety through timely fault indication, and increased operational uptime from reduced maintenance interventions.

Application Scenarios The STP301-4-0ER-0 finds practical application across a diverse range of industries. In automotive manufacturing plants, it is installed on production line control panels to indicate the operational status of robotic cells, with red LEDs signaling emergency stops, green LEDs showing normal production, yellow LEDs warning of low material levels, and blue LEDs providing informational messages about production counts. Within the renewable energy sector, the LED indicator module is utilized in solar inverter control panels to display system states such as power generation (green), fault conditions (red), maintenance requirements (yellow), and communication status (blue), enabling technicians to quickly diagnose and address issues in solar power systems. For water and wastewater treatment facilities, the STP301-4-0ER-0 is mounted on pump control panels to indicate pump operation (green), pump failure (red), low-level warnings (yellow), and system standby (blue), ensuring efficient water management and timely response to potential overflow or drought conditions. In discrete manufacturing settings like electronics assembly lines, the LED indicators guide operators through production stages, with green signaling component placement completion, red indicating placement errors, yellow warning of component shortages, and blue showing quality inspection readiness, thereby improving production throughput and reducing defect rates. Additionally, in building automation systems, the STP301-4-0ER-0 is used in HVAC control panels to display system operation (green), filter change reminders (yellow), fault alarms (red), and temperature setpoint achievement (blue), contributing to energy-efficient and comfortable building environments.
