Intrinsically safe [Ex ia] NAMUR Compatible Input Module
One Digital Input per Connector – M12 Female
Input module is for use with NAMUR certified intrinsically safe (IS) sensors. The module can be placed in
any G3 I/O position available but must be used in conjunction with appropriate clips with partition plates
(see picture on page 8-71). This module is for use with (IS) sensors (certified to EN 60947-5-6) where
the sensor is placed within the hazardous area, (e.g. ATEX 0-20, 1-21, and 2-22). This [Ex ia] module is
part of the G3 electronics platform, which is designed to reside outside of the hazardous environment or
in Zone 2-22, inside of a cabinet with appropriate ingress protection. The partition plate clips, used
between standard G3 modules and [Ex ia] modules, are required to maintain ATEX approval. The 8.2 V
sensor supply for each input connector is short circuit protected.
