Installation
4�6�3 DC Powered Analyzer
Analyzer - Power Supply Connections (DC Version)
The OXYvisor control unit can operate using 24 VDC +/-10%.
must be from a Class2 or LPS source, OR that a fuse (1 A) will be required in the installation.
Please note that the 24VDC version of the analyzer is a 4-wire device. It has
separate wiring for power and signal (not a loop powered device).
