Product Description

The IC660BBA101 is an Input Block in the GE Fanuc Genius I/O Series. Its rated voltage of 115 VAC/125 VDC. The purpose of this block is to monitor temperature input from Resistive Temperature Detectors (RTDs). Two types of RTD blocks available include 15 VAC/125 VDC RTD Block IC660BBA101 and block IC660BBA 124/48 VDC RTD. The only difference between the two is power supply.

IC660BBA101 detects temperature changes as low as one-tenth of a degree. One important feature is the six RTD compatible inputs arranged in three sets of two inputs per piece. Input sets are completely isolated and independent. These independent input circuits are used with RTDs made from copper, platinum, or nickel.

Like other RTD Input Blocks in this series, IC660BBA101 is self-regulating. A multiplexer is assigned to switch the A/D converter between RTD inputs and reference resistors. Block IC660BBA101 measures resistance from 0 – 5,000 ohms. To configure the block for processing data in Fahrenheit, Celsius, ohms, or counts, a handheld monitor is required. IC66HHM501D is perfectly compatible with block IC660BBA101 and can also be used in block setup and control. Features of this block include configurable input filter time, linearization, alphatype, RTD resistance, and alarm thresholds. Do not re-calibrate your RTD block; it is factory-calibrated. Automatic diagnostics on the block include open wire detection and internal fault detection. The user may disable or enable fault reporting circuit-by-circuit.
 

IC660BBA101 block performs circuit diagnostics. It alerts the user when calibration readings are not tolerable or when connections between RTD and the terminal assembly are incorrect. Faults are reported to both the handheld monitor and the CPU. However, the user can configure the block circuit by circuit to report faults to the handheld monitor. It is not necessary to clear most fault conditions because they rarely interrupt block functions. The user must clear High or Low Input Alarm faults before detection can restart. Because input filter time RTD blocks are factory-calibrated, they do not need successive recalibration. Installation and run-time errors like input short detection, inner fault detection, wiring error detection, and/or open wire detection can automatically be identified by IC660BBA101 block automatic diagnostics.
