FLEX Ex Frequency Input Module 7
Publication 1797-5.9 - June 2010
ATEX Directive
These products are tested in conjunction with associated I/O modules to
meet the Council Directive 94/9/EC (ATEX) Equipment and Protective
Systems Intended for Use in Potentially Explosive Atmospheres by applying
the following standards:
 EN60079-11:2007, Explosive atmospheres - Part 11 : equipment
protection by intrinsic safety "i"
 EN60079-0:2006, Electrical apparatus for explosive gas atmospheres -
Part 0 : general requirements
 EN 60079-26 : 2004, Electrical apparatus for explosive gas
atmospheres - Part 26 : construction, test and marking of Group II
Category 1 G electrical apparatus
 EN61241-0 : 2006, Electrical apparatus for use in the presence of
combustible dust - Part 0: General requirements
 EN61241-11:2006, Electrical apparatus for use in the presence of
combustible dust – Part 11: Protection by intrinsic safety 'iD'
Inputs
The frequency input module has 2 input channels. Each input can accept
inputs from magnetic pickups or proximity probes. Each input channel has 2
input selections: frequency input or gate input. Do not apply any
nonintrinsically safe signals to this module.
The channels in this module are electrically connected to each other.
When using an intrinsically safe electrical apparatus according to EN
60079-11, the European directives and regulations must be followed.
IMPORTANT
When interconnecting several lines, you must consider the total
accumulated power and check for intrinsic safety.
