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 8-62).
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.
