Wiring the outputs
Wire the discrete output
The discrete output can indicate the flow direction, transmitter zeroing in progress, pressure input failure, faults, event 1
or event 2. You can wire the discrete output to use internal or external power. See Micro Motion 9739 MVD Transmitters:
Configuration and Use Manual for more information on configuring the discrete output for events.
or event 2. You can wire the discrete output to use internal or external power. See Micro Motion 9739 MVD Transmitters:

Procedure
Use terminals 22 and 16 for the discrete output.
The discrete output, frequency/pulse output, and discrete input share terminal 16 as a common return.
• If wiring the discrete output to be internally powered, see Figure 5-9.

• If wiring the discrete output to be externally powered, see Figure 5-10. For recommended resistor versus supply
voltage, see Figure 5-11.
Do not exceed 30 VDC input. Excessive current will damage the transmitter. Terminal current must be
less than 500 mA.
