Complete List Of User Differences Of Revisions А, В And B.01 For E20-10 Module - L-Card E20-10 User Manual

2.1. Complete list of user differences of revisions А, В
and B.01 for E20-10 module
Since 2008 L-Card has decided to release E20-10 of revision В with advanced useful
quality.
All E20-10 modules of 2006 and 2007 production years should be related to revision А (see
label on the body bottom), since 2008 L-Card has started to produce E20-10 of revision В.
In 2013 L-Card has started to release revision B.01 with extended power voltage range.
Revisions B and B.01 are not differed in program. Revision B.01 specified on label on body bottom
face, new power voltage range "+8.0...+40 V" is specified on body top cover.
E20-10 module has signed in 2017 as modification in L-CARD Measuring voltage converter
series.
