Frequently Asked Questions about IS200ISBBG1AB

There are two groups of the ISBB model; what are the differences between the IS200ISBBG1AB and ISBBG2 models, if any?

Due to a lack of documentation from General Electric, it is unknown whether or not there are any major differences between the two ISBB groups. From a visual inspection of the two models, there seem to be no differences. Both models have relays, potentiometers, and LED indicators. For more information on the potential differences between the two groups, refer to any available GE Documentation.

What are the LEDs on this model used for?

The two LEDs on this model, which are green and yellow, labeled Interlock Active and XMIT Data, are used to indicate the status of the data and activity. It is unknown whether or not the LEDs will always be solid or if, at any point, they will flash to indicate that a fault is present. The XMIT Data LED is used to help the user indicate that the model is either receiving or putting data out; there is a plug on this model labeled XMIT Data out which is used for data outputs. 

Product Description

The IS200ISBBG1AB functions within the Mark VI as an InSync Bus Bypass Card. The board is marked along its top edge with the board number and the code 6BA01. The code 6DA01 appears along the bottom edge of the board. This small card is factory drilled at multiple locations. Four drill holes are ringed with a conductive material. These four drill holes (E1, E2, E3, E4) will be used to mount the board to DIN rails.

The IS200ISBBG1AB has two relays, side-by-side, just left of the center. The board has two rectifier coils, two LED indicators (one green, one yellow,) and one jumper switch. Settings for the jumper are noted directly below the component in a small table on the board’s surface. LEDs are labeled Interlock Active (green) and Xmit Data (yellow.) There is a single integrated circuit that functions as a voltage comparator. The board has diodes, resistors, and capacitors.

Connectors on the IS200ISBBG1AB include three plugs. These are marked P1 through P3 and are labeled Full Duplex, Xmit Data Out, and Rcv Data In. The board has one short terminal strip with two screw connections. This is labeled 24 VDC Input. Data sheets, manuals, or user guides from GE will provide more information if needed. Static-sensitive boards are shipped from AX Control and protected by anti-static wraps.

Reviews For IS200ISBBG1AB

Internal Review

One of the downsides of the IS200ISBBG1AB is the availability of the model. Due to no longer being actively produced by General Electric, the model can be difficult to find, as well as documentation regarding what models it can work with, what the functions of the board are, etc. - AX Control Tech
