IC660BBS100

**IC660BBS102 replaces IC660BBS100**

The IC660BBS100 is an isolated I/O Block manufactured by GE Fanuc that provides eight circuits in four isolated groups (each having two circuits). Its rated voltage is either 115 VAC or 125 VDC with a current of 2 Amps. The isolation is rated to withstand 250 VAC/VDC between any two groups.

Electronic fusing is built in for every circuit being used as an output. Should a short circuit occur, the circuit will shut down after five microseconds. However, the block can easily be restarted from the CPU or from a handheld monitor. Additional diagnostic checks performed by the block include unexpected shutdown, power overload, detection of load absence, and over temperature. An isolated block can be configured as input only, output only, or a combination of the two.

Each circuit comes with its own LED responsible for indicating threshold voltage for a circuit configured for input. For an output circuit, it indicates the mode configured by the CPU. Some of the configurable features of the IC660BBS100 block include bus switching control, presence of a dual power circuitry (i.e., both DC and AC circuitry), an input filter time that is easily selectable ranging from 10 ms to 100 ms, test capability of output pulse, and CPU redundancy type.

The block is 100% compatible with a hand-held monitor (models IC660HHM501 and IC660HHM500). IC660BBS100 is also compatible with any bus controller manufactured by GE Fanuc.  During field wiring, connections are made using simple tools such as standard screws and screwdrivers. Each terminal block accepts 1 AWG size #12 or two AWG #22 wires. Also accommodated are ring terminals with a width of up to 0.27 inches with a minimum opening for screw size #6. This block has been replaced by IC660BBS102.

The IC660BBS100 Isolated I/O Block belongs to the GE Fanuc Genius I/O series of I/O modules. It comes with 4 isolated groups of 2 I/O circuits each for a total of 8 I/O. It is compatible with the IC660HHM501 hand-held monitor which can be used for the configuration of the block. This I/O block is backward compatible with the previous block versions. The IC660BBS100 Isolated I/O Block has an LED to indicate the operating status of each of its I/O circuits. Additionally, each circuit of the module has a built-in thermal sensor. The block’s diagnostic facilities are made to report all the faults of the module to the hand-held programmer so that the users can take the necessary corrective actions as quickly as possible.    

The IC660BBS100 Isolated I/O Block has an I/O circuit which is rated to operate at a nominal voltage of 115 Volts AC or 125 Volts DC. It can perform a variety of diagnostic checks including no-load detection, over-temperature detection, open-wire detection for the tri state inputs, and overload detection, and it can shut down to protect itself.  This isolated I/O block can act as an input-only, output-only, or combination block. Once it is configured as an input-only block, all the circuits act as regular inputs and tri-state inputs. The configurable features of the IC660BBS100 Block are its output pulse test capability, CPU redundancy, bus switching module control, and selectable input filter times. It also comes with an internal electronic short circuit trip for safety. The heat dissipation rating of the module is 18.8 Watts. Its dimensions are 8.83 x 3.5 x 3.94 inches and its approximate weight is 4 pounds. It is recommended to configure the module as a combination block to have a mix of inputs and outputs.
