GSDA-AI-A8
P3 and P6 Terminal Block Hook-Up Diagram
NOTE: THE GSDA-AI-A8 DOES NOT SUPPLY LOOP “EXCITATION VOLTAGE”. If the flowmeter, SCADA
system, etc. does not have a Loop Excitation supply, an ex9 to +36 VDC power source must be
provided, capable of at least 50mA for each of the two 4-20 mA Current Loops (Input and Output), as
shown in the diagram below. Additionally, if the Input and Output must be isolated from each other,
two excitation supplies may be needed.
