IC660BBS101 Isolated I/O Block from GE Fanuc
The IC660BBS101 belongs to the GE Fanuc Genius I/O series. This block delivers 8 I/O circuits across 4 isolated groups. Each group contains two circuits. Block to block isolation reaches 1500 Volts. You can configure this module for input-only, output-only, or mixed operation. The default setting is input-only.
Key Technical Specifications
The IC660BBS101 operates at 115 VAC or 125 VDC nominal voltage. AC voltage range runs from 93 to 132 Volts. DC voltage range spans 105 to 132 Volts. AC frequency range sits at 47 to 63 Hertz. Each circuit handles 2 Amps of current. Typical input processing time is 2 milliseconds for AC voltage. For DC voltage, processing time is 0.8 milliseconds.
Power and Heat Dissipation
Control power for the IC660BBS101 comes from I/O device voltages wired to block terminals. Separate terminals exist for driving internal electronics. Peak heat dissipation reaches 16.8 Watts with all 8 circuits as inputs. With all 8 circuits as outputs at 2 Amps, heat dissipation hits 45.6 Watts. Consider this thermal output when placing the block inside an enclosure.
LED Status Indicators
The IC660BBS101 comes with a full array of LEDs. One LED displays the overall I/O block status. Another LED shows if I/O are enabled. Each circuit has its own dedicated LED. For a circuit configured as an input, the LED indicates threshold voltage. For a circuit configured as an output, the LED shows the state commanded by the CPU. These indicators help you monitor operation at a glance.
Environmental and Mechanical Ratings
The IC660BBS101 operates between 32°F and 140°F (0°C to 60°C). Storage temperature ranges from -40°F to 212°F (-40°C to 100°C). Dimensions measure 224.4 x 84.8 x 99.3 millimeters. Weight equals 1.8 kilograms (approximately 4 lbs). These compact dimensions fit standard industrial enclosures.
Wiring and Field Connections
Each terminal block accepts one AWG #12 wire. It also accepts two AWG #14 wires. Minimum recommended wire size is AWG #22. Spade or ring terminals up to 0.27 inches wide fit the terminal block. You can connect up to five power sources to the terminal assembly. Use standard tools like screwdrivers for all connections.
Compatibility Information
The IC660BBS101 works fully with handheld monitor IC660HHM501. You can use it with any GE Fanuc bus controller, including PCIM or QBIM models. Backward compatible blocks include IC660CBS100, IC660BBS100, and IC660BS101. These earlier versions share similar functionality with the IC660BBS101.
Application Examples
Use the IC660BBS101 where isolation between circuits matters. Choose it when manual switches wire in parallel with outputs. The lack of failed switch diagnostics makes it ideal for these parallel wiring schemes. Mixed I/O applications benefit from its flexible configuration. Systems with both AC and DC devices can use its dual voltage support.
Comparison with IC660BBS100
The IC660BBS100 reports failed switch diagnostics. The IC660BBS101 does not. This is the main difference between these two models. Choose the IC660BBS101 when you need to ignore commanded versus actual state mismatches. Choose the IC660BBS100 when you want those diagnostic messages. Both blocks share similar voltage, current, and isolation ratings.

FAQ
Does the IC660BBS101 report failed switch diagnostics?
No, this block does not report failed switch diagnostics. It ignores differences between commanded and actual internal switch states.
When should I use the IC660BBS101 instead of the IC660BBS100?
Use the IC660BBS101 when field wiring such as manual switches connects in parallel with block outputs. The lack of failed switch diagnostics suits this application.
What is the default configuration of this block?
The default setting is input-only. You can change it to output-only or combination using a handheld monitor.
How many power sources can I connect to the IC660BBS101?
You can connect up to five power sources to the terminal assembly. This includes I/O device voltages and separate control power inputs.
Is the IC660BBS101 compatible with modern bus controllers?
Yes, it works with any GE Fanuc bus controller, including PCIM and QBIM models. It also works with handheld monitor IC660HHM501.
