Wiring Transducers with 15-Pin D-Connectors
Input Power Connections
Figured 2-9. Input Power (15-Pin D-Connector)
Note: Use separate, dedicated wires for pins 9 and 10 to the power supply com-
mon on meters and pins 9,10 and 3 on controllers.
Output Signal Connections
Standard output for all transducers is a 0-5 VDC signal, which di-
rectly corresponds to the 0 to 100% mass flow full scale range.
Output signals are linear and require a minimum load resistance of
1000 Ohms (4-20 mA output 600 Ohms maximum loop resis-
tance).

Figure 2-10. Output Signal (15-Pin D-Connector)
Notes:
1. Panel meter or read-out device should be wired to be at the
same ground potential as the power supply.
2. 4-20 mA output signal is ground referenced (“non-isolated”).
Warning: Do not apply any external voltage to this loop.
