2.4.4 Process Current

The figure below shows the wiring hookup for Process Current 0 – 20 mA.

Figure 2.8 Process Current Wiring Hookup

(Internal and External Excitation)

When configuring your instrument, select Process Type in the Input Type

Menu (see Part 3).

2.4.5 Process Voltage 

The figure below  shows the wiring hookup for Process Voltage 0 – 100 mV, 

0 – 1 V, 0 – 10 V.

Figure 2.9

a) Process Voltage Wiring Hookup b) Process Voltage Wiring Hookup

with Sensor Excitation

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 k

Ω

, the minimum R

L

is 14 k

Ω

for 10 V process input.

When configuring your instrument, select Process Type in the Input Type

Menu (see Part 3).
