The INOR IsoPAQ-21L and IsoPAQ-22L are 1- and 2-channel loop powered isolators are used for electrical isolation of 0 to 20mA or 4 to 20mA signals to avoid measurement errors due to different voltage potentials or ground loops in an instrument installation.

The isolators need no power supply, which contributes to reduced installation costs compared to isolation transmitters. The high-isolation level of 4kV provides an effective protection for downstream devices.

The 2-channel version, IsoPAQ-22L offers a very cost effective alternative combined with a high-density mounting. The high reliability and the protective separation are additional features that ensure a safe system operation.
