IC660BBD101  Low Leakage Input/Output Block

IC660BBD101 is a GE Fanuc Low Leakage Input/Output Block that comes with eight discrete points/circuits and delivers 115 Volts AC. The input, as well the as operating voltage range, is between 93-132 Volts AC with a load current of 2 Amps. Each of its eight circuits can be configured for either input or output. The I/O block links multiple discrete sensors/actuators and a communication bus. The block can accommodate high input impedance. A fuse shuts down output current in the circuit if it goes beyond 30 Amps or 20 Amps for every two cycles. The circuit can later be restored by issuing a command from the CPU or a handheld monitor.

The I/O block comes with features such as input filters with selectable filter times ranging from 10ms -100ms, module control for bus switching, output feedback for voltage monitoring, pulse testing for output points, and defaults for output power-up. The IC660BBD101 block comes equipped with salient diagnostics such as voltage overload detection, power-off, and no-load detection.

LED indicators on the I/O block blink to alert the user to errors or faults such as faulty cabling, incorrect baud rate, and improper grounding among others. There is a dedicated LED for each circuit. For an output circuit, an LED, which in ON indicates that a specific circuit has complied with the command issued by the CPU. For an input circuit, however, an ON LED shows that a specific terminal has reached the threshold voltage. Error messages are generated on the handheld monitor, which helps the user attend to the fault promptly and efficiently.

The IC660BBD101 I/O block weighs 4lbs and works with model IC660HHM501 of the handheld monitor and IC693BEM331 bus controller model. During block mounting, the I/O block should be installed in a protective enclosure, which is clean and devoid of any contaminants. Furthermore, there should be adequate cooling space for the block. Mounting can be done right-side up or upside down.
