Isolation amplifiers

Choose between high-speed HSI amplifiers up to 2 MHz and DAQP amplifiers up to 300 kHz.

HSI, High-speed Amplifiers up to 2 MHz

The single channel, analog high-speed isolation amplifiers have an analog ±5 V output and provide a bandwidth up to 2 MHz. The modules plug into many DEWETRON instruments but are also popular for pure signal conditioning applications.

Key Features

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