• Absolute - output reports flow in both directions. For frequency outputs, Phase B of the
output is 90 degrees out of phase with Phase A.
• Bidirectional - output reports flow on Phase A only in the forward direction and on
Phase B only in the reverse direction.
Maximum frequency for the frequency outputs
• 1000Hz
• 5000Hz

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.
