Optocoupler output
The transmitter has an externally powered passive optocoupler output in
addition to the frequency/pulse and dual-channel frequency outputs.
The optocoupler output is derived from the primary frequency output,
and represents the same flow rate variable as the frequency/pulse
output.
Use RFT9739 terminals CN2-D10, CN2-D12, and CN2-D4 for the
optocoupler output.
• Figure 5-15 illustrates the wiring connection from the optocoupler
output to an auxiliary device.
• Signal voltage is 0-2 VDC low, 16-30 VDC high, with a 0.01 ampere
maximum sinking capability.
