IsoPAQ-11L and IsoPAQ-12L are 1- and 2-channel loop powered isolators used for electrical isolation of 0(4)-20 mA signals to avoid measurement errors due to different voltage potentials or ground loops in an instrument installation.
The INOR IsoPAQ-11L/-12L isolators need no power supply, which contributes to reduced installation costs compared to isolation transmitters. The high reliability ensures a safe system operation and low maintenance costs.
The 2-channel version, IsoPAQ-12L offers a very cost effective alternative combined with a high-density mounting.
