Atlas Copco 8433-0570-13 Stacklight ESL-04 Stack Tower Lighting

Atlas Copco's ESL-04 Stacklight (model 8433-0570-13) is a four-light stack-tower signaling unit designed for assembly lines with a high production rate, delivering rapid visual feedback to operators. The standard ESL-04 provides four configurable indicator lights and supports daisy-chain I/O bus connections to a central controller, enabling coordinated signaling across multiple workstations. Typical specs include a power draw of 9.5 W and an operating temperature range from 0°C to 50°C, making it suitable for common shop-floor environments. Atlas Copco also offers additional ESL-04 variants (for example rotating red 8433-0570-30, rotating yellow 8433-0570-35, and siren 8433-0570-40) to expand signaling capabilities while preserving the same four-light configuration in the base ESL-04 platform.
