The RayDat Ex-2 Series is intended to provide protection to low voltage signal and data circuits located in potentially explosive environments. It is intended for use on inherently safe circuits in accordance with ATEX directive. The protection module should be located as close to the end-user equipment being protected, as possible. The circuit consists of a multi-stage protector providing both common (longitudinal) mode and differential (transverse) mode protection. Coarse protection is provided using a three-terminal gas discharge tube while fine protection is provided using a high-speed bidirectional silicon stage. Care is taken to ensure coordination between these two stages without voltage or surge current blind spots occurring.
