Product summary:
The IM-Ex 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 EN 50014, EN 50020 and EN 50284 standards. 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 bi-directional silicon stage. Care is taken to ensure coordination between these two stages without voltage or surge current blind spots occurring.
