Description
55000-721MAR Marine Isolator - Negative [SIL2]
The Marine Isolator is placed at intervals on the loop and ensures that, in the case of a shortcircuit, only the section between the isolators will be affected. When the short-circuit is removed, the isolators automatically restore power and data to the isolated section.
Key Features:
- Detects wiring shortcircuits using patented technology
- Minimises disruption from short-circuits
- Automatic de-isolation on short-circuit removal
