Functional Description
IS200TDBTH6AAB is a TMR Contact input / output Terminal Board developed by GE. It is a part of Mark VIe control system. The board is a Triple Modular Redundancy (TMR) contact input/output terminal board engineered for versatile mounting options, including DIN-rail and flat mounting. This board is designed to facilitate robust and reliable control and monitoring.
Features
- Contact Inputs: The board accepts 24 group-isolated contact inputs. These inputs are supplied with a nominal wetting voltage of 24, 48, or 125 V DC, sourced externally. The flexibility in wetting voltage allows the board to be used in a wide range of applications and environments. Each contact input is equipped with noise suppression mechanisms. This feature protects against electrical surges and high-frequency noise, ensuring accurate and reliable signal detection and minimizing the risk of false triggering.
- Relay Outputs: The board provides 12 form-C relay outputs. Form-C relays, also known as changeover or double-throw relays, have a common contact that can connect to either of two other contacts, allowing for more complex control functions. The board includes an option card slot to expand the relay functions, providing additional flexibility and capability to meet specific application requirements.
- Mounting Options: The board is designed for ease of installation and versatility. It can be mounted on a DIN rail, a widely used mounting system that offers quick and secure attachment within electrical panels or control cabinets. Alternatively, it can be mounted flat, providing flexibility for installations where DIN rail mounting is not feasible.
- Safety Systems: Where noise suppression and reliable relay operations are critical for ensuring system safety and performance.
Installation
- DIN Rail Mounting: The board, along with a plastic insulator, is mounted on a sheet metal carrier. This assembly is then attached to a standard DIN rail. DIN rail mounting is a common method used in industrial environments due to its simplicity and reliability, allowing for quick installation and secure attachment within electrical panels or control cabinets.
- Panel Mounting: Alternatively, plastic insulator can be mounted on a sheet metal assembly that bolts directly into a cabinet. This method provides additional stability and is suitable for installations where DIN rail mounting is not possible or preferred.
- Wiring Connections: The board features two sets of 48 terminal blocks for wiring connections, typically using 18 AWG wires. This wire gauge is commonly used in industrial applications due to its balance of flexibility and durability.
- TB1 and TB2 Terminal Blocks: The upper set of terminals, labeled TB1, connects to the relay portion of the board. This set handles the output signals, allowing for control and activation of external devices. The lower set of terminals, labeled TB2, connects to the contact input circuits. This set receives the input signals from various sensors and devices, facilitating monitoring and control operations. The screw assignments for the two sets of terminals (TB1 and TB2) are identical to those found on the SRLY relay board and the contact input terminal board. This consistency in design simplifies the wiring process and ensures compatibility with existing systems.
- Shield Termination: To ensure proper shielding and minimize electrical interference, shielded cables should be terminated on a separate bracket. This practice helps in maintaining signal integrity and protecting the system from noise and electromagnetic interference (EMI).

Frequently Asked Questions
What is IS200TDBTH6AAB?
It is a TMR Contact input / output Terminal Board developed by GE under the Mark VIe series.
What are the mounting options for the board?
DIN rail mounting using a sheet metal carrier. Panel mounting is done by bolting the sheet metal assembly into a cabinet.
What type of wires should I use for connecting to the terminal blocks?
It is recommended to use 18 AWG wires for connecting to the terminal blocks on the board. This wire gauge is suitable for most industrial applications due to its flexibility and durability.
How many terminal blocks are on the board, and what do they connect to?
The upper set, TB1, connects to the relay portion of the board. The lower set, TB2, connects to the contact input circuits.
Are the screw assignments on the terminal blocks unique?
No, the screw assignments for the TB1 and TB2 terminal blocks are identical to those on the SRLY relay board and the STCI contact input terminal board. This consistency helps simplify the wiring process.
