Product Description

The IC660BBD022 is a 24 VDC Source I/O, 16 Circuit, 2/3 Wire Sensor Compatible Block of GE Fanuc series 90-30 PLCs. It is among the discrete and analog blocks that belong to this series. It works with 24 VDC and is used with two and three wire solid state sensors and electromechanical sensors. Each of the 16 circuits, the block can work as an input, output, or tristate input, and no other components are required for configuration. Power supply is provided to all circuits by the block.

The IC660BBD022 has various configurable features. Among these are output test capability, selectable input time filter, output power up defaults, and output hold last state or default. The block has the ability to protect the system in case of electronic short circuit and over temperature. It can detect a failed switch, no load, and open wire in tristate inputs. In case there is overload, it detects the problem and shuts down.

This block can replace all its previous versions when a compatible electronics assembly is connected. The block should be installed in a protective case in a location with no airborne contaminants alongside adequate cooling and air flow.

IC660BBD022 needs a reliable grounding system. Terminals of this block interface with #12 wire or two #14 wires. There are 22 terminals on this block. The serial bus connects 1 to 4, and terminals 6 to 21 can be used as inputs or outputs by selecting the DC+ or DC- side of the terminal. DC power connects to terminals 5 and 22. When replacing an electronics assembly, the user must be careful because there is danger of electrical shock.

This I/O block is DC-powered, and it is an intelligent device that is configurable for use as an actual device or as a sensor. The unit has configurable features including the output power default, output pulse test capability, and the selectable input filter time. The GE Fanuc IC660BBD022 I/O block comes with diagnostics as well as safety features that alert the users about operational errors. This unit can detect over-temperature, overload, short circuit, failed switch, and no-load errors. The I/O block is compact in size and portable. It saves panel space and it has dimensions of 8.83 x 4.42 x 3.56 inches.

The GE Fanuc IC660BBD022 Genius I/O source I/O block features 16 configurable input and output circuits. It also features the "Unit OK" and the "I/O Enabled" LED indicators which are designed to light up whenever there is normal application activity going on in the block. There is also a monitoring port that connects to a hand-held programmer device. In addition to that, this I/O block is connected to a personal computer that operates on the Windows operating system. The GE Fanuc IC660BBD022 I/O block has a power dissipation rating of 68.8 Watts when it is operating at a current rating of 2 Amps. This unit produces an all-out ripple of 10 percent during normal operation.
