The IC660BBS102 is a 115 Volt AC/125 Volt DC Isolated Genius I/O Block by GE Fanuc Emerson. It has an isolation that is rated to withstand 250 Volts AC/DC continuous between any group and ground or between any two groups. This IC660BBS102 block in particular reports a ‘failed switch’ diagnostic if any of the outputs have a commanded state that is different than the actual state of the block internal switch. Block specifications for this hardware include a size of 8.83 x 3.34 x 3.91 inches, or 22.44 x 8.48 x 9.93 centimeters. The approximate weight of the IC660BBS102 is 4 pounds, or 1.8 kilograms. The block has LED indicators for Unit OK and I/O Enabled. Block to block isolation is 1500 Volts and it has a required control power of 8 Watts maximum (block only). Operating voltage (AC) for the IC660BBS102 is 93-132 Volts AC and 105-132 Volts DC for direct current.

Input specifications for the IC660BBS102 include an input processing time (typical) of 2 milliseconds + filter for alternating current and 0.8 milliseconds + filter for direct current. Selectable input filter times are 10 to 100 milliseconds in 10-millisecond increments. Output specifications for this piece of hardware include a maximum switching frequency of once per second and a voltage drop (at 2 Amperes) of 2.5 Volts; Voltage drop at 30-Ampere inrush is 10 Volts. Environmental specifications include an operating temperature range between 0 and 60 degrees Celsius and a storage temperature range between -40 and 100 degrees Celsius; humidity is 5% to 95% (non-condensing). This IC660BBS102 block has a vibration of 5-10 Hertz 0.2” (5.08 millimeter) displacement, 10-200 Hertz at 1G.

According to the manufacturer, the IC660BBS102 can continuously sustain 250 volts alternating current (AC)/direct current (DC) within any two groups: two grounds, or between a group & ground. The transient rate for the block is 2000 volts for 10 seconds. Alternating current/direct current circuit voltage, CPU redundancy, default for output power, and a programmable input filter that supports from 10 milliseconds to 100 milliseconds are all configurable features.

The isolated I/O block should work as long as terminals 5 and 6 are powered. The output circuits are protected by the switching device's short circuit level sensor. As "open equipment," Genius I/O blocks must be mounted in a protective enclosure that is clean, free of airborne pollutants, and has appropriate cooling airflow.

For a fresh block, outputs are programmed to report No-Load circumstances. The mounting screws on the block should not be utilized as the sole means of grounding the block. Upside down or right side up are both acceptable positions for the block to be mounted in. It is important to leave at least 2 inches between each block. The IC660HHM501 handheld monitor is well suited with the IC660BBS102 block. The block is also compatible with any bus controller from GE Fanuc.

Previous versions of this I/O terminal block are compatible with the following blocks: the IC660CBS100, the 1C660BBS100, and the IC660BBS101. One AWG 12 or AWG 14 cable wires during field wiring are accepted by all terminals. The ring terminals that measure up to 0.27 inches can be accommodated in terminals labeled 1 to 4. All terminals should be torqued to 6 inches/lb. The IC660BBS102 output block enables CPU redundancy as well as the voltage from an AC or DC source.
