IS200TDBTH8A is a Contact Input / Output Terminal Board developed by GE. It is a part of Mark VIe control system. To ensure reliable and accurate contact input readings, the board incorporates noise suppression technology. This feature shields the contact inputs from surge voltages and high-frequency noise, safeguarding the system against potential electrical disturbances and enhancing the overall signal integrity. One of the key features of the board is its capability to accept 24 group isolated contact inputs. These inputs are specially designed to handle various types of signals and are provided with a nominal 24, 48, or 125 V DC wetting voltage from an external source. This allows the board to accommodate a wide range of input signal voltages, providing greater adaptability for different industrial setups.
- On the output side, it offers 12 form-C relay outputs. These relays provide both normally open and normally closed contacts, making them suitable for a variety of control and switching applications. The form-C relay configuration offers versatility, allowing the board to interface with different types of equipment and devices in the industrial setup.
- Moreover, the component is designed with expansion capabilities in mind. It can accept an option card that enables the expansion of relay functions, providing users with the flexibility to customize and extend the board's capabilities according to specific application requirements. This modularity empowers users to tailor the board to suit the needs of their complex and evolving industrial systems.
- The TMR architecture ensures enhanced reliability and fault tolerance. By incorporating three redundant modules, the board can continue to function seamlessly even if one or two modules experience a failure. This high level of redundancy adds a layer of robustness to the overall system, reducing downtime and enhancing system reliability in critical industrial processes.
The board, along with a plastic insulator, is designed for versatile mounting options to ensure ease of installation in industrial setups. It can be assembled on a sheet metal carrier, which is then mounted on a DIN rail. Alternatively, with the insulator can be mounted on a sheet metal assembly that securely bolts inside a cabinet. This flexibility allows users to select the most suitable mounting method based on their specific application and available space.
- To facilitate efficient connections, the board features two sets of 48 terminal blocks, each accommodating typical #18 AWG wires. The upper set of terminals, known as TB1, is dedicated to connecting to the relay portion of the board. On the other hand, the lower set of terminals, referred to as TB2, is used to establish connections with the contact input circuits.
- The screw assignments for both sets of terminals, TB1 and TB2, are identical to those found on the SRLY relay board and the STCI contact input terminal board. This consistency simplifies the wiring process and allows for seamless integration with existing systems using these terminal boards.
- To ensure optimal performance and protection against electromagnetic interference, shields associated with the module should be terminated on a separate bracket. This segregation of shields helps maintain signal integrity and reduces the risk of noise or interference affecting the overall performance of the board and the connected equipment.
- The combination of the module with its plastic insulator and various mounting options, along with the conveniently arranged terminal blocks and shield termination strategy, makes it a highly adaptable and reliable solution for industrial control systems. Its ability to seamlessly interface with existing terminal boards further enhances its versatility, allowing users to expand their control systems with confidence and efficiency. Whether mounted on a DIN rail or inside a cabinet, the board stands as a robust and dependable component, serving critical roles in contact input/output applications in industrial automation.
- The module features a contact input function and on-board signal conditioning, similar to that found in the STCI contact input terminal board. However, the module is scaled to support various wetting voltage options, specifically 24 V DC, 48 V DC, and 125 V DC wetting voltages. This versatility allows the board to accommodate different input voltage requirements in industrial applications.
- The input wetting voltage range varies based on the wetting voltage selection. For 24 V DC wetting voltage, the input wetting voltage range is set between 16 V DC and 32 V DC. For 48 V DC wetting voltage, the range is between 32 V DC and 64 V DC. Finally, for 125 V DC wetting voltage, the range extends from 100 V DC to 145 V DC. This wide range of wetting voltages ensures compatibility with various control systems and voltage sources.
- The threshold voltage for contact sensing circuits is set at 50% of the selected wetting voltage. This threshold voltage establishes the point at which the module recognizes the input signal as either open or closed, enabling accurate and reliable contact input sensing.
- Regarding the input currents for contact inputs, the first 21 circuits are resistance-limited to a maximum of 2.5 mA. This limitation protects the circuit and ensures that the current remains within safe operating limits for these specific inputs. For circuits 22 through 24, the input currents are resistance-limited to a slightly higher value of 10 mA, again maintaining a safe and controlled current level.
