FUNCTIONAL DESCRIPTION:

IS200DTBBH1A is a Contact Input Expansion Termination Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Contac Input Termination Module (DTBB) is situated in Q11, Q21, and Q51. In the same digital core, DTBB connects the final 46 contact inputs to TCDA. To enable failsafe contact input functionality, the inputs can be adjusted in the TCDA IO Configuration to invert the contact sense.

DTBB CONNECTORS:

• JRR - Connects the contact inputs to the TCDA board.
• JY - Receives 125 V dc power from the DTBA board.
• JRS/T - Typically not used.

DTBB HARDWARE CONFIGURATION:

• BJ1 through BJ5 ñ Isolates the contact inputs for the test (from the 125 V dc).

CONTACT INPUTS:

DTBB terminal boards have jumpers that can be used to isolate field grounds by disconnecting the interrogation voltage. They are connected in groups of eight contact inputs. These jumpers should only be changed while the turbine is not running. Each contact input is optically isolated on the TCDA board, which is in Location 1 of the digital I/O core.

DTBB FEATURES:

Input Expansion: The module allows for the expansion of input capacity by providing additional input channels beyond the native capabilities of the turbine control system. This enables the integration of more sensors, switches, or control devices for comprehensive monitoring and control.

Terminal Blocks: Equipped with terminal blocks for easy and organized wiring of input devices. This simplifies installation and maintenance tasks within the control panel environment.

Compatibility: Designed to be compatible with various input signal types commonly used in gas turbine applications, including digital (on/off), analog (voltage/current), and specific protocols like Modbus or Profibus.

Signal Conditioning: Incorporates signal conditioning capabilities to ensure reliable and accurate transmission of input signals, even in challenging operational environments characterized by electrical noise or fluctuations.

FREQUENTLY ASKED QUESTIONS:

How is the Module powered and what are the power requirements?

The Module typically operates on standard power supply voltages common in control systems (e.g., 24VDC), and power requirements should align with the turbine control system specifications.

How can I determine the optimal number of input channels needed for my gas turbine control system?

The number of required input channels depends on the specific monitoring and control requirements of the gas turbine system, including the number and type of parameters to be monitored or controlled.
