Analog output - connect negative (-)DC to Terminal 8 and positive (+)DC to
Terminal 7. See
Internal power source
The 4–20 mA analog signal loop is powered from the transmitter itself.
External power source
The 4–20 mA analog signal loop is powered from an external power source. HART
multidrop installations require a 10–30 VDC external analog power source.
Note:
If a HART Field Communicator or control system will be used, it must be connected across a
minimum of 250 ohms resistance in the loop.
To connect any of the other output options (pulse output and/or discrete
input/output), consult the comprehensive product manual.
