Description

B5LA HENF327886R0001 is an industrial-grade audible and visual alarm indicator launched by ABB. Its core function is to provide clear warnings of equipment malfunctions, process abnormalities, or safety risks in industrial settings through both sound and light signals. It is a key auxiliary component for ensuring production safety and equipment maintenance. The following is detailed product information:

Product Core Positioning and Affiliation

1. Product Type: Industrial-grade integrated audible and visual alarm (including buzzer and LED indicator). “B5LA” is the series model (ABB B5LA audible and visual alarm series), and “HENF327886R0001” is the official unique material number.

2. Series Affiliation: Belongs to the ABB Industrial Safety and Signal Indication product family, compatible with various industrial equipment (such as inverters, control cabinets, machine tools) and automation systems, and supports long-term stable operation in harsh industrial environments.

3. Core Function: When equipment triggers a fault (such as overload or short circuit), process parameters exceed thresholds (such as high temperature or high pressure), or safety doors are not closed, it simultaneously emits audible alarms and flashing light signals to quickly alert on-site personnel for timely intervention, preventing the escalation of accidents or production interruptions.

Core Functions and Features

1. Dual Alarm Mechanism:Sound Alarm: Built-in high-decibel buzzer, the alarm volume can cover noisy industrial environments (typical loudness 85~105dB, depending on the model), supports continuous or intermittent alarm modes (some versions can switch via external signals).Light Alarm: Equipped with high-brightness LED beads, supporting warning colors such as red and yellow (red is the mainstream configuration, in line with industrial safety warning practices), the light mode is flashing (frequency about 1~2Hz), with a long visible distance (typically clearly visible within 50 meters).

2. Industrial-Grade Durability:The casing is made of flame-retardant ABS or PC material, with impact-resistant and corrosion-resistant properties, protection rating up to IP65 (some versions IP67), dustproof and splash-proof, suitable for complex environments like workshop oil, dust, and humidity.The internal circuit is designed to resist vibration, and components have a wide temperature tolerance, capable of stable operation next to high-frequency vibrating equipment (such as motors and compressors).

3. Flexible Adaptation and Installation:Power supply is compatible with industrial standard voltages, primarily supporting 24V DC (suitable for centralized control cabinet power supply), some versions support 110V AC/220V AC (direct connection to mains or equipment power supply).Installation methods are flexible, supporting panel cut-out installation (embedded) or bracket-mounted installation (external), suitable for various equipment housings or control cabinet layouts, with installation hole diameters and dimensions meeting industrial universal standards.

4. Low Power Consumption and Long Life:LED lifespan up to 50,000 hours or more, buzzer designed without mechanical wear, overall mean time between failures (MTBF) ≥ 100,000 hours, reducing replacement and maintenance costs.Low standby power (only LED indicator dim), moderate power consumption during alarm status, does not add extra total device energy consumption.
