Product Description


General: The IC660BBA021 is a 24/48 volt DC RTD Input Block from the GE Fanuc Genius I/O Series. This block monitors temperature input from Resistive Temperature Detectors (RTDs). The IC660BBA021 block groups input circuits in three rows, each with two circuits.


Input Circuits: Each input circuit can be used with RTDs made from platinum, nickel, or copper. It has sensors in place to report input data to the CPU in engineering units of tenths of degrees Celsius, tenths of degrees Fahrenheit, tenths of Ohms, or counts, depending on how it is configured.


Calibration: The IC660BBA021 is factory-calibrated to detect temperature variations as low as one-tenth of one degree. Because it is factory-calibrated, it does not require subsequent recalibration.


Resistance: The IC660BBA021 measures resistance from 0 to 5,000 ohms. Values for parameters can be set such as input filter time, alpha type, alarm thresholds, linearization, and RTD resistance.


Measures: The IC660BBA021 is 8.83” (22.44cm) high, 3.5” (8.89 cm) wide, and 3.94” (10 cm) deep. Unit OK and I/O Enabled LEDs conveniently display block status.


Troubleshooting: Diagnostic software in the IC660BBA021 automatically captures the reasons for installation or run-time errors. These errors might be electrical shorts, wiring mistakes, range threshold violations, or alarm conditions. To facilitate troubleshooting, they trigger abbreviated but easily understandable messages such as “Overrange”, “Input Shorted”, “Internal Fault detection”, “Overrange and Underrange”, as well as High and Low input alarms on a handheld monitor. Fault reporting can be enabled or disabled circuit by circuit.


Note: Severe radio frequency interference in the environment (10 V/m or higher as described in IEC 801-3 of 1984) will degrade the accuracy of block measurements without generating error messages. It is important to note that the IC660BBA101 is identical to the IC660BBA021 block except it features a power supply capable of working with a higher voltage range (115 VAC/125 VDC).
