Wiringtheoutputs
• If the pressure transmitter requires a power supply greater than 13.6 V, or if other loop devices are required, you
can use an external source to power the pressure transmitter. Use terminals S and 23 (see Figure 5-14).

Notes
• Terminal S (MA SIG IN) is the signal input to the 9739 MVD transmitter.
• Terminal 23 (SIGNALGND) is the return. You must connect terminal 23 directly to the negative (-) terminal of the external
power supply.
• If digital communications between the pressure transmitter and the 9739 MVD transmitter is required, use terminals
17 (PV+) and 18 (PV−) (see Figure 5-15).
