20Ma Output Card (20Maos) - Electro Industries Shark 200 Installation & Operation Manual

7.5: 20mA Output Card (20mAOS)

The 20mA card transmits a standardized 0-20 mA signal. This signal is linearly pro-
portional to real-time quantities measured by the Shark® 200 meter. The current
sources need to be loop powered. The outputs are electrically isolated from the main
unit.
