Module

The  PX454S  is  a  full  function  DMM

suitable  for  use  on  a  variety  of

platforms  with  the  family  of  C&H

carriers. This DMM is based upon a

24  bit  Sigma-Delta  A/D  converter

with  on-chip  notch  filter.   This

frequencies  (or  filter  frequencies)

between 10 Hz and 1 KHz providing

varying  resolutions.  

The  core

measurement  section  is  optically

isolated and shielded.

This unit also features a position for

adding one single-wide M-Module.
