The IC660BBD110 is a 115 Volt AC Discrete Input Block that is manufactured and branded by GE Fanuc Emerson. It provides an interface to 115 Volt AC discrete input sensors, with two banks of eight circuits each (16 total). Block specifications for this hardware include dimensions of 8.83 x 3.34 x 3.91 inches, or 22.44 x 8.48 x 9.93 centimeters. The IC660BBD110 weighs approximately 4 pounds, or 1.8 kilograms. It is equipped with I/O Block LED indicators for Unit OK and I/O Enabled. LEDs for each circuit reflect the state of input (logic side). Input to ground or serial bus isolation is 1500 Volts while heat dissipation is 28 Watts maximum with 16 inputs on at full current. Operating voltage (single source) is 93-132 Volts AC and it has a frequency of 47-63 Hertz. Required power for the block alone is 80 Milliamperes maximum block current plus 200 Milliamperes maximum input circuit current. Terminal board rating is 5 Amperes and power supply dropout time is 1 cycle (16.7 milliseconds at 60 Hertz, 20 milliseconds at 50 Hertz).

Environmental specifications for the IC660BBD110 include an operating temperature between 0 and 60 degrees Celsius and a storage temperature between -40 and 100 degrees Celsius. Humidity should remain within the range of 5% to 95% (non-condensing). Vibration is 5-10 Hertz with 0.2” displacement and 10-200 Hertz at 1 G. Input specifications include an input impedance of 11.6K Ohms and an input processing time (typical) of 1 millisecond (plus selectable filter time). Selectable input filter times are 10 to 100 milliseconds in 10 millisecond increments.

The IC660BBD110 is a self-contained I/O block with sixteen (16) input points manufactured by GE Fanuc. This Module enables the Genius bus communication protocol, which enables it to be put in close proximity to machines without the requirement for a baseplate, CPU, or communication adaptor. This device is an intelligent input module that permits daisy-chaining and communicates directly with the controllers or communication adapter on the same network.
The IC660BBD110 input channels are intended to accept signals with an operating voltage of 93-132VAC, a frequency range of 47-63 Hertz, and a nominal voltage of 115VAC. It features a configurable threshold of 25% to 85% for both the ON and OFF modes. Additionally, this module includes internal channel diagnostics that are capable of detecting open and shorted wires. Additionally, both diagnostic characteristics have programmable thresholds ranging from 25% to 85% and a fixed threshold of 10% to 90%, respectively. This Module features a 1 millisecond input processing time and software-configurable input filters ranging from 10 to 100 milliseconds in increments of 10 milliseconds. This input filter is capable of suppressing distortion and signal bounces.
The IC660BBD110 module holds 4 pounds / 1.8 kg in weight and dimensions  8.83"(Height) x 3.34" (Width) x 3.91" (Depth). It has LED indications for unit readiness, I/O enablement, and individual inputs. Internally, it features a 1500V isolation between the ground and the serial bus. The IC660BBD110 is allied to Genius Bus through the terminal’s block located beneath the LED indicators on the Module. This is a three-pin terminal that is accessible via a hinged door. This Module may be placed in either orientation (right-side-up or upside-down).
 Advanced diagnostics and configurable thresholds are included with the IC660BBD110 discrete input block. Contact closure connections with devices like switches, limit switches, and push buttons are some of the most frequent input connections. It is capable of connecting to both two-wire and three-wire proximity switch inputs.  To provide device protection, the software may be used to configure the IC660BBD110 discrete input block to detect shorted and open-wire defects.
