This evaluation unit connects to four CES safety read heads, processing their signals for use in safety-related monitoring circuits. It forms part of a coded-magnet safety switch system, typically applied where multiple guard doors or access points on a machine or panel require centralised safety monitoring. The unit is suited to industrial automation installations where several read head inputs must be consolidated into a single evaluation point.
