6ES7650-8AR60-0AA0
Within ET 200PA SMART, Siemens 6ES7650-8AR60-0AA0 converts eight thermocouple inputs or four resistance-temperature channels and transfers their values to the backplane.
Channel parameters on 6ES7650-8AR60-0AA0 select thermocouple, RTD, resistance, or voltage behavior. Internal compensation, an external Pt100, or a defined reference temperature supplies the cold-junction value.
The 20-pin field interface of 6ES7650-8AR60-0AA0 groups non-isolated channels behind a backplane isolation barrier. Parameterized diagnostics identify overrange, underrange, and transmitter wire-break conditions.
