GE Fanuc IC660BBA101 Genius RTD Input Block
Six-channel RTD input block for platinum, nickel and copper resistance temperature detectors.
01Model Profile
IC660BBA101 is a Genius I/O RTD block with six input circuits arranged as three isolated pairs. It accepts platinum, nickel or copper RTDs and linearizes each circuit according to the selected sensor type.
Temperature or resistance values can be returned in tenths of degrees Celsius, tenths of degrees Fahrenheit, tenths of ohms or counts. Alarm thresholds, RTD resistance, alpha type, linearization and filter time are configurable per application.
The block is factory calibrated and includes open-wire, shorted-input, wiring-error, overrange, underrange and internal-fault diagnostics. The 115 VAC/125 VDC supply version is electrically different from the 24/48 VDC IC660BBA021 only at the block power supply.

03RTD Channel Organization
- Six circuits are divided into three groups of two.
- Each input is linearized for its configured RTD material and alpha type.
- Engineering-unit reporting avoids treating temperature inputs as raw discrete data.
04Sensor Diagnostics
Configuration point
High and low alarms are configurable for each circuit.
Installation check
Factory calibration removes routine field recalibration from the normal setup.
