Overview
The QTC70L-IOL is a Ø70 mm IO-Link programmable LED tower light for industrial signaling. It features a modular, lock-type assembly for tool-free addition and removal of modules, optional built-in high-volume (Max.100 dB at 1 m) or waterproof (Max.85 dB at 1 m) buzzer variants, and IO-Link V1.1 connectivity for plug & play integration in smart manufacturing (Industry 4.0) systems.

Key product features

• Modular LED steady/flashing signal tower with lock-type structure for tool-free module changes.
• Separate color filter lens located inside the outer lens for clear signaling; translucent filter for comfortable viewing when off.
• Four operating modes for environmental adaptability:
  • Simple Mode: basic on/off control of individual light sources.
  • Advanced Mode: configure on/off and strobe timing for each light source.
  • Level Mode: percentage-based input to control light output for process operations.
  • Demo Mode: sequential demonstration of functions.
• Seven light source operations available: On, Slow Blink, Medium Blink, Fast Blink, Strobe 1, Strobe 2, Strobe 3.
• Integrated IO-Link technology (Version 1.1) with data transmission at 38,400 bps (COM2); Connector: M12-5Pin (Male) - Class A for standardized plug & play.
• Optional buzzer variants: High-volume buzzer (Max.100 dB at 1 m) and Waterproof buzzer (Max.85 dB at 1 m).
