DS3800HIOA1C1E

Product Description

The GE Input Isolator Board DS3800HIOA1C1E features a hole in each corner for installing the board with screws. The GE Input Isolator Board DS3800HIOA1C1E also is populated with a microprocessor and multiple erasable programmable read-only (EPROM) modules. The board has 1 34-pin connector that is accessible from the edge of the board. It also is populated with test points.

If the board is not operating at full capacity first inspect the fuses. Replace any that are blown. If too much power is present in the circuit or other unusual activity occurs, the fuse will blow to protect the circuit. This removes power from the circuit and the function provided by the circuit will be lost.

Another source of information is to use the test points which are located on the surface of the board. They are available for use by a qualified servicer to test the function of the board. Each test point is associated with a circuit on the board. With use of a properly calibrated testing device, the servicer can check the health of a circuit. The servicer must have knowledge of the board circuitry and the proper safety precautions. In some cases, a board can be repaired and installed in the drive.

The testing can only be performed when the board is removed from the drive. The board must be placed on static protective material. This might be a mat designed for the purpose or on a flattened static protect bag.
