New Dy­nam­ic Input Card with Volt­age and IEPE sup­ply

The IfTA input mod­ule AD4PS to mea­sure volt­ages and cur­rent sig­nals with gal­van­ic iso­la­tion as well as switch­able IEPE sup­ply and volt­age source on each chan­nel.

The AD4PS is a new input mod­ule to mea­sure volt­ages and cur­rent sig­nals. In ad­di­­tion the new card of­fers gal­van­ic iso­la­tion as well as a switch­able IEPE sup­­ply and volt­age source on each chan­nel. Thus, ac­­tive sen­­sors and other mea­­sure­­ment chain com­po­­nents such as iso­la­­tion am­­pli­­fiers can be run di­rec­t­­ly. Espe­­cial­­ly when there are large dis­­­tances be­tween the con­trol room and the mea­­sur­ing site, gal­­van­ic iso­la­­tion is re­quired. With the IEPE sup­­ply, a 2-wire line is suf­­fi­­cient for the power sup­­ply, since the sup­­ply and the sig­­nal are led over the same line. Espe­­cial­­ly in ap­­pli­­ca­­tions with large num­bers of mea­­sur­ing sites, IEPE enor­­mous­­ly sim­­pli­­fies the in­­stal­la­­tion ef­­fort and mea­­sure­­ment setup. Thanks to the flex­i­ble push-in con­nec­­tors, in­­stal­la­­tion ca­bles can be laid di­rec­t­­ly with­­out the need for time-con­­sum­ing con­nec­­tor as­sem­bly.
