Ex Versions

1. Description

These versions of the converter are suitable for installation in a hazardous area where
intrinsically safe outputs are required.

This converter has passive outputs, which also has the benefit of utilizing the multi-drop
feature of HART®. The outputs are galvanically separated from each other.
Please ensure that you know which converter options you have, to use the correct wiring
diagram.

2. Output Options

The following output options are available:

G. 

 1 x 4 -20mA and 1 x Pulse output

H. 

 1 x 4 -20mA and 1 x Status output

K.        1 x 4 -20mA and 1 x Control input

L. 

 2 x 4-20 mA

           M.       1 x 4-20mA and PROFIBUS PA

N.        1 x 4-20mA and Foundation Fieldbus (pending)

Note: HART® is available on the first current output in all cases except options M and N.

Wiring the Converter:

Note:
Supply compartment is
separated from output
terminals
