IsoPAQ-21L / IsoPAQ-22L 1 & 2 Channel Loop Powered Isolators
Isolators for 0(4) - 20 mA signals with high isolation and protective separation
IsoPAQ-21L/22L are a 1 & 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 isolators need no power supply, which contributes to reduced installation costs compared to isolation transmitters. The high isolation level of 4 kV provides an effective protection for downstream devices.
The high reliability and the Protective Separation are additional features that ensure a safe system operation.
