HSI Series Modules

HSI series modules are analog high-speed isolation amplifiers with bandwidth up to 2 MHz. All are single channel, easily exchangeable by the user and have an analog ±5 V output. The modules plug into many DEWETRON instruments but are also popular for pure signal conditioning applications.

 

HSI series modules offer multiple ranges and selectable filters which are set by push buttons or by a simple configuration software – when used in DEWETRON instruments the module setup is included in DEWESoft data acquisition software. Versions with different convenient sockets for signal connection are available. Models with multi-pin sockets offer sensor supply for single cable sensor connection.

HSI series isolated amplifiers ensure precise, safe and reliable measurements in all applications.

 

Key features:

  • High isolation up to 1.8 kVRMS
  • High bandwidth up to 2 MHz
  • ±5 V conditioned signal output
  • Single channel modularity
