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.
