The TM3TI4 (screw terminal block) / TM3TI4G (spring terminal block) expansion module feature 4 analog input channels with 16-bit resolution.
The channel input types are:
o0...10 V
o-10...+10 V
o0...20 mA
o4...20 mA
oK thermocouple
oJ thermocouple
oR thermocouple
oS thermocouple
oB thermocouple
oE thermocouple
oT thermocouple
oN thermocouple
oC thermocouple
oPT100
oPT1000
oNI100
oNI1000
For information on the diagnostic codes produced by each input type, refer to Analog I/0 Modules Diagnostics.
For further hardware information, refer to TM3TI4 / TM3TI4G.
NOTE: If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in EcoStruxure Machine Expert, you may damage the analog circuit.

INOPERABLE EQUIPMENT |
|
Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. |
|
Failure to follow these instructions can result in equipment damage. |
For each input, you can define:
