The Vital 1 safety controller does not require programming. It uses the DYNlink system, which allows up to 30 safety devices to be connected in series to the same circuit, while achieving PL e. This enables a single Vital to supervise all safety functions on many machines that otherwise would have required a programmable safety controller or multiple safety relays. Typical applications are machines with multiple doors, hatches or emergency stop buttons. Vital is also commonly used to supervise all emergency stops for larger machine lines. The DYNlink circuit is a unique solution that uses one single channel to achieve up to Cat. 4/PL e. Vital sends out a square wave signal that is inverted by each safety device. A connection between B1 and S1 sets if Vital should receive a non-inverted signal, i.e. an even number of devices are connected (no shunt indicates an odd number). Vital checks the returning signal 200 times/second and a fault such as a short circuit will be detected before any safety device is used. Vital can only be used with DYNlink safety device, such as Eden DYN, and devices with a TINA adapter.

• Vital safety controller excels at supervising multiple safety devices on the same machine, since up to 30 safety devices can be connected in series
• Easy to reach hightest safety level: The DYNlink solution makes it possible to maintain the highest level of safety with up to 30 sensors connected in series
• The use of only one safety module without any programming simplifies commissioning and replacement. Significantly fewer components needed to achieve PL e/SIL 3
• Integrated LED diagnostics reduces down time when troubleshooting, detachable connection blocks simplify replacement or repair
