2.3.4 Process Current
The figure below shows the wiring hookup for Process Current 0 – 20 mA.
Figure 2.6 Process Current Wiring Hookup
(Internal and External Excitation)
When configuring your instrument, select Process Type in the Input Type Menu
(see Part 3).
2.3.5 Process Voltage
The figure below shows the wiring hookup for Process Voltage 0 – 100 mV,
0 – 1 V, 0 – 10 V.

(with Sensor Excitation and without Sensor Excitation)
R
L
- Voltage limited resistor, which allows to convert 24 Vdc internal excitation
voltage to the appropriate process input value. For instance: if the potentiometer
value is equal to 10 kΩ, the minimum R
L
is 14 kΩ for 10 V process input.
When configuring your instrument, select Process Type in the Input Type Menu
(see Part 3).
