DYNlink is an ABB-specific sensor-communication and cabling solution that makes it easy to reach the highest level of safety using a minimum of cables and PLC inputs.

Using Vital, the DYNlink circuit allows up to 30 DYNlink devices to be connected in series to a single input while still reaching up to Cat. 4/PL e/SIL3. This dramatically decreases the number of inputs and cables needed, since to reach the same level with standard two-channel safety devices, two inputs are necessary and series connection is not possible. (10 sensors would require 20 inputs.) Compared to OSSD signals, DYNlink only requires half the amount of inputs.

Compatible controllers
