What it represents
A PLC temperature input connects a documented RTD, thermocouple or compatible sensor through the selected module. Sensor type and conductor count determine its wiring and configuration.
How to read it
- Preserve thermocouple polarity or RTD lead arrangement in the schematic.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State sensor type
- Show conductor/polarity arrangement
- Reference channel scaling
A distinction that matters
A dedicated temperature input is different from an analog input receiving a conditioned transmitter signal.
