Overview
The GE IS200VRTDH2DAA, also cataloged as the IS200VRTD RTD Input Terminal Board, provides a physical interface for multi-channel RTD field signals within GE Mark VI and Mark VIe Speedtronic control platforms. The board terminates field wiring and routes temperature measurement signals toward the corresponding I/O circuitry.
Suffix Breakdown & Model Matrix
The supplied data identifies IS200VRTDH2DAA as the complete part number and identifies IS200VRTD as the base type. It also identifies H2DAA as the hardware revision. No further suffix-level functional definitions are provided, so no additional matrix interpretation is assigned.

GE Industrial Control and I/O Interface
The IS200VRTDH2DAA handles physical temperature-sensor wiring rather than performing standalone temperature control. RTD signals enter through the terminal interface, then the connected I/O circuitry processes the sensor information for the control system.
The board supports standard RTD inputs, including Platinum 100-ohm sensors. Therefore, the field wiring must match the sensor type and terminal assignment defined by the applicable system documentation.
The multi-channel terminal arrangement supports high-density temperature signal termination. However, the supplied data does not specify the exact channel count, channel isolation method, excitation current, measurement accuracy, or conversion resolution.
Frequently Asked Questions
Q: What type of field signal does the IS200VRTDH2DAA terminate?
A: It terminates RTD temperature sensor signals, including standard RTD types such as Platinum 100-ohm sensors.
Q: Does the supplied data specify the exact number of RTD channels?
A: No. The supplied information only identifies a multi-channel terminal block configuration and does not provide a specific channel count.
Q: Does the supplied data confirm hot-swap operation?
A: No. Hot-swap capability is not specified. Installation and replacement should follow the applicable GE Mark VI or Mark VIe system procedure.
Field Installation Guidelines
Install the board in the designated GE Speedtronic rack or cabinet location. Confirm the board identification and terminal assignments before connecting field wiring.
Route RTD wiring separately from high-voltage power conductors where practical. This arrangement reduces the potential for electrical interference in low-level temperature measurement circuits.
Connect RTD conductors according to the applicable system wiring diagram. Verify sensor type, polarity where applicable, and terminal continuity before applying system power.
Terminate cable shields according to the cabinet grounding design. Avoid uncontrolled shield connections that can create unintended ground-current paths.
Keep field wiring mechanically secure and provide appropriate strain relief at the terminal interface. Do not apply excessive force to the terminal connections or PCB assembly.
Before commissioning, verify each connected RTD circuit for continuity and correct channel assignment. Confirm that the control system receives the expected temperature signal before placing the associated measurement loop into service.
