2.3.4 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).

2.3.5 Process Voltage

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

0 – 1 V, 0 – 10 V.

with Sensor Excitation without Sensor Excitation

RL - Voltage limiting resistor, which allows conversion of the 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).
