The IC660BBD101 is a 115 Volt AC Low-Leakage I/O Block by GE Fanuc Emerson. Features for this Block include selectable input filter time from 10 milliseconds to 100 milliseconds, output feedback for monitoring, output powerup defaults, outputs hold last state or default, pulse testing for outputs, and bus switching module control. Specifications for the IC660BBD101 include a size of 8.83 x 3.34 x 3.91 inches, or 22.44 x 8.48 x 9.93 centimeters; it has an approximate weight of 4 pounds, or 1.8 kilograms. I/O Block LEDs are included for Unit OK and I/O Enabled. The IC660BBD101 has a block to block isolation of 1500 Volts and a heat dissipation of 16 Watts maximum with 8 inputs and 43.5 Watts maximum with 8 outputs on at 2 Amperes. Standby power with all inputs and outputs off is 8.5 Watts. The IC660BBD101 has a single source operating voltage of 93-132 Volts AC and a frequenct of 47-63 Hertz; power supply dropout time is 1 cycle (16.7 milliseconds at 60 Hertz, 20 milliseconds at 50 Hertz).

Additional specifications include a circuit output current (steady state) of 2 Amperes RMS and 25 Amperes peak for maximum inrush current up to 2 cycles; maximum inrush current for 2-6 cycles is 14 Amperes peak. The IC660BBD101 has a maximum block output current of 15 Amperes at 35 degrees Celsius and 7.5 Amperes at 60 degrees Celsius. Output diagnostics are available for short circuit, overload, no load, failed switch, and overtemperature. The IC660BBD101 has an operating temperature range between 0 and 60 degrees Celsius and a storage temperature between -40 and 100 degrees Celsius. Humidity is 5% to 95% (non-condensing) and vibration is 5-10 Hertz 0.2” (5.08 millimeters) displacement, 10-200 Hertz at 1G.

The IC660BBD101 I/O block of GE Fanuc is a discrete I/O block designed for GE Fanuc's Genius I-O product range. It has an I/O rated power of 115 Volts Alternate Current and runs on Alternate Current electricity. This discrete I/O block is a customizable and sophisticated device that may function as a communications bus connection for discrete devices such as discrete actuators or sensors. This I/O block comprises eight identical circuits, each of which may be configured as either output and input are regulated at 115 volts Alternate Current. The IC660BBD101 I/O block includes numerous helpful functions such as an input filter time adaptable between 10 and 100 milliseconds, output feedback for monitoring, pulse examining for all outputs, and switching buses. 
Because the control power originates from the I/O device voltages that are attached to the terminals, the IC660BBD101 discrete I/O block does not require a separate block power source. It has a voltage range of 94 to 132 Volts Alternate Current and a frequency range of 47 to 63 Hertz. The discrete I/O block IC660BBD101 weighs 4 pounds and is 8.8 x 3.3 x 3.9 inches in size. Electronic fuses safeguard all 8 circuits on this I/O block, shutting them down within 5 milliseconds if the output current exceeds that of 30 amps when the output is turned on or if the output current exceeds 20 amps after 2 cycles. An instruction from a CPU or a portable monitor can restore circuits that have been turned off due to electronic safeguarding.
