Logarithmic output mode
Figure 15 shows in graph form the operation of the logarithmic output
mode.
Figure 15 Logarithmic output
1 Output current axis 5 Minimum output current (0-4 mA)
2 Source value axis 6 50% output current
3 High value 7 Maximum output current (20 mA)
4 50% value
Bilinear output mode
Figure 16
shows in graph form the operation of the bilinear output mode.
Figure 16 Bilinear output
1 Output current axis 5 Low value
2 Source value axis 6 Minimum output current (0-4 mA)
3 High value 7 Knee point current
4 Knee point value 8 Maximum output current (20 mA)
Configure relays
The Normally Open (NO) and Common (COM) relay contacts will be
connected when an alarm or other condition is active. The Normally
