Details

The GE Digital I/O Board DS200TCDAH1B features one microprocessor and multiple programmable read only memory (PROM) modules. It also contains 1 block of 10 LEDs and 2 50-pin connectors. The GE Digital I/O Board DS200TCDAGH1B also is populated with 8 jumpers and 1 LED that is visible from the side of the board. The GE Digital I/O Board DS200TCDAH1B also features 2 3-pin connectors. One 3-pin connector has the ID JX1 and the other has the ID JX2.

The IDs assigned to the 8 jumpers are prefixed with JP. For example, one jumper is assigned the ID JP1. Another jumper is assigned the ID JP2, and so on. The test points also have a prefix assigned to the IDs. The prefix for the test points is TP. For example, one test point is assigned the ID TP1. Another test point is assigned the ID TP2. With the use of a qualified testing device, a servicer can test the individual circuits on the board and pinpoint a fault that might be repairable.

DS200DTBA and DS200DTBB are other boards that are installed in the drive. And both receive signals from the GE Digital I/O Board DS200TCDAH1B through the 50-pin connectors. One 50-pin connector is assigned ID JQ and the other 50-pin connector is assigned ID JR. Connector JQ connects to the JQR connector on DS200DTBA. 50-pin ribbon cables provide the signals between the boards. Connector JR receives the contact input signal from DS200DTBB.

The DS200TCDAH1BGD General Electric Digital I/O Board features one microprocessor and multiple programmable read-only memory (PROM) modules. It also contains 1 block made up of 10 LED lights and a pair of 50-pin connectors along with 8 jumpers and 1 green LED that is visible from the side of the board. The PROM modules are removable from the board and they reside in a socket embedded on the board. When replacing the board or if you are in the process of replacing the PROM module for any reason, you can obtain a hand tool that is expressly designed for removing and installing the PROM modules.

It is important to remember that the PROM module is easily corrupted or destroyed by static buildup. Protect yourself and the equipment by always wearing a wrist strap when you work on the board or any other board or component in the drive. When the wrist strap is connected to a metal desk or chair, the static is attracted to the grounded object and leaves your body and the board.
