Output for FODO1 and Digital Output1 (Group 1 on the CPU Module) share a common ground 
and have 50V isolation. FODO2 and FODO3 (Group 2 on the CPU Module) share a common 
ground and have 50V isolation. This allows an output to be connected to a different flow 
computer. The outputs are opto-isolated from the CPU Module and have a withstand voltage of 
at least 500V rms dielectric.

Analog input settings
The Daniel 3410 Series Gas Ultrasonic Flow Meter has the capability to sample analog 
temperature (Analog Input 1) and pressure (Analog Input 2) with 4-20 mA signals. These analog  
input signals are configured to sink. The two independent analog input circuits are configured 
for conventional 4-20 mA service. Also, 24VDC isolated power supply connection is provided for 
an external power source. Refer to the Field wiring diagram DMC - 005324 in 
.
