Available with IO-Link Connectivity

Our 856T Control Tower™ Stack Light system gives you maximum flexibility in meeting the widest range of applications with a reduced number of components. This system uses a modular design that incorporates brighter LED illumination and a broad offering of sound technologies. All signals in the system are 24V AC/DC powered, which means that just three power modules can cover the entire system. IO-Link enabled versions provide real-time insight into the status of your control system.
