Datasheet
picoPakI-I
4-20mA Isolator
The picoPak™ I-I is a very compact isolator for
4-20mA loops. The output is loop powered. The
module is perfect for eliminating ground loops
and providing increased protection for PLC and
DCS analog inputs.
Isolation is optical. This means the output load
does not effect the voltage drop across the input
(the voltage drop is a near constant at 3.5V).
Features:
• just 8mm wide
• mounts on 32mm and 35mm DIN rails
• 2000V isolation
• user adjustable span and zero adjustments
• CSA, CE and Class 1 Div 2 approved
