Figure 51 shows the output current depending on the process value, the set low value and the set high value with an output range of 4–20 mA.
Figure 51 Output current with an output range of 4–20mA
1 | Output current (OC) | 5 | Low value (LV) |
|
|
|
|
2 | OC=f(PV) | 6 | 0mA |
|
|
|
|
3 | Process value (PV) | 7 | 4 mA |
|
|
|
|
4 | High value (HV) | 8 | 20 mA |
|
|
|
|
The output current is determined according to formula (2):
(2) OC = f(PV) = | ⋅ | |
| HV – LV |
|
where: OC=Output current PV=Process value LV=Low value HV=High value
