GE Fanuc IC660BBA103 Genius Thermocouple Input Block
Six-input thermocouple block with three isolated pairs and configurable cold-junction compensation.
01Model Profile
IC660BBA103 acquires six thermocouple or low-level voltage inputs in three isolated groups. It supports J, K, T, E, B, R, S and N thermocouple types and linearizes measurements for the selected thermocouple characteristic.
Each channel can use the internal cold-junction sensor, an external voltage or current temperature signal, or a user-defined compensation value. The external XJV path is scaled at 1 mV per degree Celsius and XJI at 1 µA per kelvin.
The block reports open wire, high and low alarm, overrange, underrange and internal fault conditions. Input values are delivered in configured temperature units, millivolts or counts.

03Thermocouple Pairing
- Two measurement channels share each isolated group.
- Every channel retains its own thermocouple type and alarm settings.
- Twelve bytes of input data carry six two-byte measurements per bus scan.
04Cold-Junction Compensation
Configuration point
The processor adds the compensation value before thermocouple linearization.
Installation check
Open-wire supervision also covers remote cold-junction inputs.
