I/O modules

The GE IS200DTAIH1A IS200DTAIH1ABB printed circuit board manages thermocouple input signals for Mark VI systems. This board processes low-level voltage signals from temperature sensors. It connects directly to the VME backplane for reliable data transfer. You can use either model number as a direct replacement.

Detailed Technical Specifications

This GE IS200DTAIH1A IS200DTAIH1ABB printed circuit board measures 300 mm in length. Its width reaches 205 mm across the main surface. The total height goes up to 34 mm with all components installed. This unit weighs approximately 0.67 kilograms for secure mounting.

Key hardware parameters include:

• Complete Model: GE IS200DTAIH1A IS200DTAIH1ABB

• Component count: 152 individual electronic parts

• Connector ports: Two 50-pin ribbon cable headers

• Energy storage: Seven aluminum capacitors (470 µF each)

• Mounting system: Four reinforced corner brackets

• PCB layers: Six-layer low-noise construction

• Thermocouple inputs: 24 isolated differential channels

• Input types: J, K, T, E, R, S, and B thermocouples

• Cold junction: Eight onboard compensation sensors

• Sampling rate: 50 Hz per channel simultaneously

• Resolution: 18 bits for high-precision readings

The GE IS200DTAIH1A IS200DTAIH1ABB printed circuit board stores moderate residual charge after power-off. Therefore, technicians must wait thirty seconds before handling the board. Each input channel includes built-in open-circuit detection. Moreover, each channel provides common-mode voltage rejection up to 250 V.

Application and Installation

The GE IS200DTAIH1A IS200DTAIH1ABB printed circuit board mounts horizontally in a Mark VI analog I/O rack. It requires a compatible termination board for thermocouple wiring connections. This board accepts signals from exhaust gas and bearing temperature sensors. Consequently, you can monitor critical thermal points across the turbine.

Signal Processing and Reliability

This board filters electrical noise from every thermocouple input channel. Its six-layer PCB design minimizes thermal gradients across the board. The GE IS200DTAIH1A IS200DTAIH1ABB includes automatic cold junction compensation for each input group. Therefore, you maintain accurate temperature readings without manual offset adjustments.

Always power down the entire rack before inserting or removing this board. Match the ribbon cable orientation carefully to avoid pin damage. The board features diagnostic LEDs for power, communication, and channel fault status. Furthermore, its conformal coating protects against dust and moisture ingress.
