Functional Description
The IS200BAIA Bridge Application Interface Board (BAIA) provides isolation and
an earth ground reference for all signal inputs from user terminal boards. It outputs
customizable and application to the processor board, as follows:
•Six isolated, differential, universal 115 V ac, 50/60 Hz sinusoidal (or 24−105 V
dc) discrete logic
•Three separately controlled form C relay contacts are provided for discrete
outputs.
•Two bipolar (±10V) analog input channels, each with a differential amplifier
followed by a synchronous voltage-controlled oscillator (VCO).
•VCO pulse trains transmitted differentially to isolate the analog inputs

GEI-100268A

2GEI-100268
The BAIA converts digital inputs from the DSPX to analog outputs: channels A
and B are available for customer use at the terminal board; channels C and D are
used to drive panel meters. The BAIA provides an RS-232C I/O interface
between the DSPX and the drive's keypad and PC connections.
Application Data
The BAIA board includes plug connectors to interface with other devices in the
IGCT drive. The BAIA board also includes adjustable hardware (jumpers),
testpoints, and LED indicators. The board contains no fuses. See Figure 1 for a board
layout diagram that shows the location of major board components.

Indicators
The BAIA front panel has one green LED, IMOK. This LED is turned on during user
read and write activity of a specific location. It will automatically go out if no read or
write activity is detected.

GEI-100268 3
Testpoints and Jumpers
The BAIA board provides three testpoints for signal measurement (see Figure 1).
These testpoints are accessible through the top opening in the board's front panel (for
factory use only).
Testpoint Jumper Functions
1 AIN1 Buffered analog input 1
2 AIN2 Buffered analog input 2
4 ICOM12 Common for analog inputs
Four analog input jumpers are provided (in two pairs) for a given analog input circuit,
A (VIN) and B (4−20 mA). The jumper should be in either the 4−20 mA position or
in the VIN position.

I/O Connectors
The BAIA board connects to and mounts to the control rack backplane through two
connectors, P2 and P1. See Figure 1 for locations and Tables 1 through 7 for pin
descriptions.

Renewal/Warranty Replacement
How to Order a Board
This information helps ensure
that GE can process the order
accurately and as soon as
possible.
When ordering a replacement board for a GE drive, you need to know:
•How to accurately idenify the part
•If the part is under warranty
•How to place the order
Board Identification
A printed wiring board is identified by an alphanumeric part (catalog) number
located near its edge. The following diagram explains the structure of the part
number.
The board’s functional acronym, shown in Figure 3, normally is based on the board
description, or name. For example, the BAIA board is described as the Bridge
Application Interface board.

Warranty Terms
The GE Terms and Conditions brochure details product warranty information,
including warranty period and parts and service coverage. The brochure is
included with customer documentation. It may be obtained separately from the
nearest GE Sales Office or authorized GE Sales Representative.

12 GEI-100268
Placing the Order
Parts still under warranty may be obtained directly from the factory:
GE Industrial Control Systems
Product Service Engineering
1501 Roanoke Blvd.
Salem, VA 24153-6492 USA
Phone: [phone]
Fax: [phone]
Renewals (spares or those not under warranty) should be ordered by contacting the
nearest GE Sales or Service Office. Be sure to include:
•Complete part number and description
•Drive serial number
Note All digits are important when ordering or replacing any board.
The factory may substitute later versions of boards based on
availability and design enhancements. However, GE Industrial Control
Systems ensures backward compatibility of replacement boards.
Onboard Firmware
Each new board is shipped with the firmware already installed (when applicable).
The onboard EEPROM containing this firmware is not intended for removal or
programming in the field. If a board fails because of firmware or EEPROM
problems, or if an upgrade is needed, the board must be replaced.
How to Replace the Board
Handling Precautions
To prevent component damage caused by static
electricity, treat all boards with static sensitive
handling techniques. Wear a wrist grounding strap
when handling boards or components, but only
after boards or components have been removed
from potentially energized equipment and are at a
normally grounded workstation.
Printed wiring boards may contain static-sensitive components. Therefore, GE ships
all replacement boards in antistatic bags. Use the following guidelines when
handling boards:
•Store boards in antistatic bags or boxes.
•Use a grounding strap when handling boards or board components (per above
Caution criteria).

GEI-100268 13
Replacement Procedures
To prevent electric shock, turn off power to the
board, then test to verify that no power exists in the
board before touching it or any connected circuits.
To prevent equipment damage, do not remove,
insert, or adjust board connections while power is
applied to the equipment.


To remove the BAIA board from the rack
1. Make sure that the drive in which the board resides has been deenergized.
2. Open the drive’s cabinet door, and using equipment designed for high voltages,
test any electrical circuits before touching them to ensure that power is off.
3. Carefully remove the board from the rack, as follows:
a. Loosen the screws at the top and bottom of the faceplate, near the
ejector tabs. The screws are captive in the faceplate and should not be
removed.)
b. Unseat the board by raising the ejector tabs.
c. Using both hands, gently pull the board from the rack. (Note jumper
positions).
To install the new (replacement) board in the rack
Because Innovation Series boards are designed for
specific rack slots, inserting the BAIA board into
the wrong slot can damage the electronics.
1. Slide the board into the correct slot in the rack.
2. Begin seating the board by firmly pressing the top and bottom of the faceplate at
the same time with your thumbs.
3. Finish seating the board in the slot by starting and then tightening the screws at
the top and bottom of the faceplate. Tighten the screws evenly to ensure that
the board is seated squarely.
Note If the BAIA board must be configured in any way, refer to the
applicable User's Manual for the drive/source for procedures.
