Temperature measurement with a sensor in 4-wire technology
With p4108[0...5] = 3, you sense the signals from a sensor in 4-wire technology at a 4-wire
connection at terminals 3(+) and 4(-).
The measuring cable is connected at terminal 1(+) and 2(-).
Measurement with up to 12 channels
Temperature measurement with two sensors in 2-wire technology
With p4108[0...5] = 1 you can acquire the signals from two sensors in 2-wire technology.
The first sensor is connected at terminal 1(+) and 2(-).
The second sensor (number = first sensor + 6) is connected at terminals 3(+) and 4(-).
When connecting two sensors in 2-wire technology to terminal X531, the first sensor is
assigned to temperature channel 1 and the second sensor is assigned to channel 7 (1+6).
Note
Connection diagram for 12 temperature channels
The temperature sensors connected to a TM150 are not numbered consecutively. The first 6
temperature channels retain their numbering of 0 to 5. The other 6 temperature channels are
consecutively numbered from 6 to 11, startin
g at terminal X531.
Example of 8 temperature channels:
● 2x2 conductors at terminal X531: p4108[0] = 1 ≙ sensor 1 is at channel 0 and sensor 2 is
at channel 6
● 2x2 conductor at terminal X532: p4108[1] = 1 ≙ sensor 1 is at channel 1 and sensor 2 is
at channel 7
● 1x3 conductor at terminal X533: p4108[2] = 2 ≙ sensor 1 is at channel 2
● 1x3 conductor at terminal X534: p4108[3] = 2 ≙ sensor 1 is at channel 3
● 1x4 conductor at terminal X535: p4108[4] = 3 ≙ sensor 1 is at channel 4
● 1x2 conductor at terminal X536: p4108[5] = 0 ≙ sensor 1 is at channel 5
