Atlas Copco's ESL-04 STANDARD Stacklight, part number 8433-0570-13, is a five-lamp signaling module designed for real-time error indication on high-volume assembly lines. Operating from a 24 V DC supply with a 24 V I/O bus and the ability to daisy-chain, it consumes 9.5 W and measures 75 mm in height, 479 mm in length, and 100 mm in width, weighing about 1.2 kg. The ESL-04 Stacklight provides rapid visual signals (and audible cues where configured) to report errors back to the operator, enabling quick correction at the workstation and reducing rework.
