INOR IsoPAQ-21L/-22L 1- & 2-channel Loop Powered Isolators

IsoPAQ-21L/-22L 1- & 2-channel Loop Powered Isolators for 0(4)-20 mA Signals with High Isolation and Protective Separation

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.

The 2-channel version, IsoPAQ-22L offers a very cost effective alternative combined with a high-density mounting.

Features

• Input to output galvanic isolation
  Protection against erroneous measurements due to parasitic voltages or ground loops
• 1- and 2-channel versions
  Allows for optimal cost efficiency
• No power supply required
  Reduced wiring saves installation costs
• Low voltage drop
  Input voltage drop of less than 2 V reduces impact on the primary current loop
• Protective Separation
  The design and high isolation level (4 kV) provides protection for service personnel and downstream devices against impermissibly high voltage
• High accuracy
  Negligible additional measurement errors in the loop
• High-density DIN-rail mounting
  12.5 mm (0.5”) housing combined with very low self heating allows for high density mounting
• Plug-in screw terminals
  Simplifies installation and maintenance
