Wire to a pressure transmitter
The 9739 MVD transmitter accepts inputs from a pressure transmitter for pressure compensation.
Because the pressure transmitter wiring is not intrinsically safe, keep the pressure transmitter wiring separated
from the power supply wiring, intrinsically safe sensor wiring, and any other intrinsically safe wiring. Failure to
comply with requirements for intrinsic safety in a hazardous area could result in an explosion.
Procedure
Choose from the following options:
• If the pressure transmitter requires a power supply less than or equal to 13.6 V, you can use the
9739 MVD
transmitter to power the pressure transmitter. Use terminals P and S to connect to a pressure transmitter (see
Figure 5-13). Do not connect these terminals to a control system.

Notes
• Terminal P (MA PWR OUT) is the power output to the pressure transmitter.
• Terminal S (MA SIG IN) is the signal input to the 9739 MVD transmitter.
