Functional Description

IS200WROGH1AAA is an optional daughter board developed by GE. It is a part of Mark VIe control system. The Mark VIe control system was designed to serve a wide array of control and protection applications, encompassing various sectors and machinery. It is particularly adept at managing and safeguarding steam and gas turbines, which are critical components in power generation. Beyond turbines, the Mark VIe extends its capabilities to the broader balance of plant (BoP) equipment within power generation facilities. This includes auxiliary systems and machinery that support the primary power generation process, ensuring seamless operation and integration of all plant components. By providing a unified control solution, the Mark VIe enhances operational efficiency, reliability, and safety across diverse power generation setups.

Features

• The board enhances the functionality of the Mark VIe system by adding fused power distribution for twelve relays, crucial for the smooth operation of control processes.
• Each fuse has isolated voltage sensing that is polarity insensitive, making it compatible with multiple voltage standards, including 24V, 48V, and 125V DC, as well as 120V and 240V AC applications. This board comes with default fuse values set at 3.15A, providing reliable power management and protection.
• From an electrical perspective, when combined with the IS200SRLYH2, the IS200WROGH1A forms a highly effective circuit. The inclusion of Connector JW2 and its connections to J1 (which are omitted for clarity in circuit diagrams) further enhances this system's performance.

Hardware Configuration

• The RS-232C standard, a well-established protocol for serial communication, specifies the use of 25 signal lines. These lines are categorized as follows: 20 lines are designated for routine operation, two lines are allocated for modem testing purposes, and three lines remain unassigned for future use or specific applications. Despite the comprehensive array of signal lines available, a typical RS-232C communication system utilizes only nine of these signal pins.
• The terminology used to describe the various signals in RS-232C communication is framed from the perspective of the data terminal equipment (DTE). For instance, the term transmit data (TD) refers to the data being sent from the DTE to the data communication equipment (DCE). This perspective ensures consistency and clarity in understanding the direction and function of each signal.
• Each signal in the RS-232C standard is transmitted using a single wire, adhering to specific conventions for sending sequential data. These data are represented as a sequence of voltage changes, with each change indicating the state of the signal. The voltage levels signify different binary states and control conditions.
  Due to the voltage requirements and potential signal degradation over distance, an RS-232C cable cannot exceed 50 feet in length. This limitation ensures reliable data transmission and minimizes the risk of signal loss or corruption, which can occur when voltages weaken over longer distances. Therefore, it is essential to adhere to this constraint to maintain the integrity and performance of RS-232C communication systems.

Frequently Asked Questions

What is IS200WROGH1AAA?
It is an optional daughter board developed by GE under the Mark VIe series.

What is the RS-232C standard?
It is a protocol for serial communication that specifies the use of 25 signal lines to facilitate data exchange between devices. It defines the electrical characteristics and timing of signals, as well as the meaning of signal voltages.

How many signal lines are used in routine RS-232C communication?
In routine communication, 20 signal lines are used. Additionally, there are two lines for modem testing and three unassigned lines, making up the total of 25 signal lines defined by the standard.

Why are only nine signal pins used in typical RS-232C communication systems?
While the standard specifies 25 signal lines, typical communication systems use only nine signal pins to simplify connections and retain essential functionality. This 9-pin configuration is adequate for most serial communication needs.
