More Information

Overview Manuals Channel Groups Conversion Modes Sensor Ranges Diagnostics and Isolation

Features:

  • Four channel groups accept eight thermocouples or four RTD/resistance circuits.
  • Selectable interference suppression changes conversion time and resolution together.
  • Backplane power, diagnostics and galvanic separation connect the field measurements to PCS 7.
Sensor voltage or resistance enters the assigned two-channel group.

The module converts the selected range according to its interference-suppression setting.

The resulting value and diagnostic state pass through the ET 200PA SMART backplane to the controller.

The Siemens 6ES7650-8AR60-1AA0 ET 200PA SMART Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Assigning sensors across four paired input groups

  • Thermocouple mode: Each group carries two thermocouple or low-voltage channels.
  • RTD mode: One resistance sensor uses both positions in its group.
  • Excitation path: The paired channel supplies measurement current for resistance mode.
  • Parameter scope: Measurement type and range are assigned per channel group.

Balancing interference rejection, update time and resolution

  • 400 Hz: Conversion takes 2.5 ms with 9 bits plus sign.
  • 60 or 50 Hz: Line-frequency rejection uses 12 bits plus sign.
  • 10 Hz: Conversion takes 100 ms with 15 bits plus sign.
  • Result path: The selected mode applies to the configured group measurement.

Matching the input circuit to voltage, thermocouple and resistance sources

  • Millivolt inputs: Ranges extend from ±25 mV through ±500 mV.
  • One-volt input: A separate ±1 V range is available.
  • Thermocouples: Types T, U, E, J, L, K, N, R, S and B are listed.
  • RTD and resistance: Pt100, Pt200, Ni100 and 150/300/600 Ω ranges use the group excitation path.

Returning field faults without joining sensor circuits to the backplane

  • Backplane supply: The module draws 5 V and requires no external 24 V source.
  • Isolation: The measurement circuitry remains separated from the system bus.
  • Diagnostics: Configured channel and module faults are reported to the controller.
  • Process interrupt: A programmed measurement event can trigger the assigned interrupt.
Description
Siemens 6ES7650-8AR60-1AA0 is a conformally coated ET 200PA SMART AI8xTC/4xRTD analog input module. It converts low-level thermocouple, voltage, resistance and RTD signals into process data for a PCS 7 automation station.

The eight input terminals of 6ES7650-8AR60-1AA0 are organized as four two-channel groups. A group can measure two thermocouple or voltage signals, while a resistance or RTD measurement uses one channel for the sensed value and the paired channel for excitation current.

Conversion in 6ES7650-8AR60-1AA0 links interference suppression to resolution and update time. The 400 Hz setting provides the shortest 2.5 ms conversion with 9 bits plus sign, whereas the 10 Hz setting extends conversion to 100 ms and provides 15 bits plus sign.

The 5 V backplane powers 6ES7650-8AR60-1AA0 without a separate 24 V field supply, and galvanic separation isolates the channel circuitry from the system bus. Programmable diagnostics and process interrupts return wiring or measurement conditions to the controller while the four channel groups share the module-level electrical limits.

Technical notes
Each resistance measurement on Siemens 6ES7650-8AR60-1AA0 occupies one two-channel group because the second channel carries excitation current.
