The applications in which signal lamps are used can vary greatly. Examples of applications can be found in mechanical and plant engineering as well as in other areas such as logistics facilities or building technology. Signal lamps make it easier to monitor operational statuses on machines, visualize cycle and clock times on conveyor belts, or provide information in the event of downtime or waiting time in the process sequence. They alert employees that they need to replenish material supplies or indicate the fill level of machinery without having to look inside the tank. But in the field of mobile automation as well, for example in automated guided vehicle systems (AGV systems), signal lamps transmit information and instructions for action. The different colors and signal patterns, such as flashing, are used to make complex machine and operational statuses easily and unmistakably visible, even from a distance. The Smart Light Tower SLT can be adapted to any conceivable application as required via IO-Link, and this without the need for time-consuming fastening of different-colored modules. This reduces the variety of variants and storage of the various individual parts.

Thanks to the IO-Link technology, the signal lamp can be customized. The parameterization of properties such as continuous light, flashing, different colors, brightness intensity or melodies can be done at any time from a control. Changes can even be made while the machine is in operation. Maximum flexibility is thus ensured without the need for mechanical conversion. The signal lamp is connected to the control level by attachment to an IO-Link master.

The signal lamp can be supplemented with a Smart Light Buzzer (SLB) acoustic buzzer module. Various melodies and a volume of 88 dB reinforce the optical signal effect and ensure that the alarm signal is noticed, even in noisy environments. If requirements change, the Smart Light Buzzer SLB can also be retrofitted at any time.
