Function Description
IS230TDBTH6A is a discrete I/O board developed by GE. It is part of the Mark VIe control system. Discrete input/output terminal boards are used to achieve TMR redundancy through DIN rail or flat mounting. Three PDIO I/O packets are connected to the controller via Ethernet and plugged into a D-type connector. This board is a TMR contact input/output terminal board that can be installed on DIN rails or flat surfaces. This board accepts 24 sets of isolated contact inputs from external sources, with nominal values of 24, 48, or 125 V DC wetting voltage. To prevent surges and high-frequency noise, the contact input has a noise suppression function. TDBT has 12 C-type relay outputs that can be extended through an optional card. The PDIO I/O package is used in conjunction with TDBT in the Mark VIe system. Three I/O packets are connected to the controller through D-type connectors and communicate through Ethernet. Three PDIO connection points are provided. JR1 will be connected to the R controller through dual controllers on the connector, JS1 to the S controller, and JT1 to both the R and S controllers. The TMR controller provides a single network connection for each PDIO, leading to the corresponding controller. Not suitable for normal operation with a single I/O package.

Installation of IS230TDBTH6A
When installing a circuit board, precise steps must be followed to ensure safe and reliable installation. This installation guide outlines the key procedures involved in installing circuit boards and wiring to achieve seamless integration.
Installing circuit boards
Circuit board and insulator placement: Circuit boards and plastic insulators should be installed on metal plate carriers. This carrier aims to provide stability and protection for the circuit board during operation.
DIN rail installation: To ensure safety and standardized installation solutions, the metal plate carrier is installed on the DIN rail. DIN rails are commonly used in industrial environments to provide a reliable platform for various control and automation components.
Sheet metal component option: Alternatively, the positive insulator can be installed on the sheet metal component and securely fixed to the cabinet. This method provides placement flexibility and is particularly useful when integrating circuit boards into existing cabinet configurations.
Wiring
Terminal block: The connection of the board is directly connected to two sets of 48 terminal blocks. These terminal blocks typically accommodate wires in the range of 24 to 12 AWG, ensuring compatibility with various wire gauges commonly used in industrial applications.
Terminal block allocation: There are two sets of terminals on the board:
Upper group (TB1): This group of terminals is mainly connected to the relay part of the board, promoting control and switching functions related to the relay.
Lower group (TB2): The lower group terminals are dedicated to contact input circuits and can connect external input signals.
Screw allocation: The screw allocation for the two terminal groups (TB1 and TB2) is the same as the screw allocation on the SRLY relay board and STCI contact input terminal board. This consistency simplifies the wiring process and allows for standardized connections across various board types.
Shielding layer termination: To ensure proper grounding and shielding, the shielding layer should be terminated using a dedicated bracket. This step is crucial for maintaining signal integrity and minimizing electromagnetic interference.

By reducing unnecessary noise, filters can ensure clearer and more accurate input readings, thereby enhancing the reliability and stability of module operation.
I/O board fault detection: equipped with a fault detection mechanism. It can detect the loss of contact input wetting voltage, which helps identify situations where the contact input has not formed correct electrical contact. In addition, the module can detect unresponsive contact inputs during testing mode, enabling effective troubleshooting and maintenance.
Maximum response time on and off: The typical maximum response time for input on and off is 25 milliseconds. This fast response time ensures timely and accurate detection and response to input changes, enabling efficient and timely control operations based on received signals.
Contact material: The contact material used in the module is silver nickel alloy. This material has excellent conductivity and corrosion resistance. Silver nickel alloy contacts provide reliable and durable connections, ensuring consistent and optimal performance even in harsh industrial environments.
Contact input
The contact input can be easily connected to the 48 terminals marked as TB2 located at the bottom of the board. These terminals are used as the main interface for connecting contact inputs to the circuit board, allowing for seamless integration into the control system.
In order to provide power to the contact inputs, the board receives contact wetting voltage through a JE1 3-pin Mate-n-lok connector located at the bottom of the board, which is very convenient. The wet voltage output terminals are all connected in series and receive a positive voltage applied to pin 1 of JE1. This arrangement ensures the necessary voltage is provided for all contact inputs to achieve normal and reliable operation.
To adapt to specific installation scenarios, TDBT boards allow users to connect a single wetting voltage lead from the board terminals to a set of remote contacts. This means that multiple contact inputs at a certain distance from the circuit board can be powered by a single wetting voltage lead. This provides flexibility for the installation process, enabling efficient wiring and reducing the number of individual wires required for long-distance connections.
Once a single wetting voltage lead reaches the remote contact group, each contact wire can be reconnected to the corresponding input on the board. This arrangement simplifies the wiring process and helps maintain the cleanliness and organization of the control system settings.
JE1 pin 3 is used as a negative voltage or return wetting voltage terminal. This pin provides the required reference voltage for the contact input, ensuring the complete circuit and normal operation of the contacts.
Configuration
The configuration design of this board is simple and user-friendly, providing flexibility and ease of use for various applications. It is worth noting that the configuration of the board does not rely on jumpers or hardware settings, simplifying the setup process and ensuring effective integration into the control system.
The WROBH1 board is one of the optional boards that can be used with TDBT, providing additional functions for relays. The WROBH1 board includes six jumpers, allowing users to individually power on or off each relay. By default, install all six jumpers to provide power to all relays on the board.
However, some scenarios may require the use of relays as dry contacts without the need for power distribution. In this case, specific relay jumpers can be selectively removed from the board. By removing the jumper from the relay, the power supply will be disconnected, effectively transforming the relay into a dry contact.
The ability to remove individual jumpers provides a customizable and effective way to adapt to different requirements and applications. Users can easily configure the board according to their specific needs, whether they need relay distribution or prefer to use relays as dry contacts.
By providing this simple jumper based configuration, the board can ensure the versatility and adaptability of various industrial control systems. The ability to modify the power allocation of each relay can accurately control the operation of the circuit board, thereby helping to optimize performance and simplify maintenance.
Overall, without the need for jumpers and hardware settings, coupled with the optional WROBH1 board with separate jumpers, a seamless and customized configuration process can be achieved. This user-friendly design helps to save time and effort during installation, and ensures reliable and precise control of contact inputs and relay outputs in industrial applications.
