Product Brief Description

The GE 369B1871G0007 is an Analog Output Terminal Board that is a component of the GE Mark VIe control system. Unlike analog input boards that receive signals, this board is specifically designed to send signals. It provides 8 channels of analog output, supporting both current (mA) and voltage (V) signals. This board serves as the physical interface for controlling various field devices, making it a critical part of the system for controlling processes in industrial applications.

Detailed Product Description

The 369B1871G0007 is a terminal board that mounts on a DIN rail or cabinet and connects to an I/O pack. Its primary function is to provide a reliable and secure termination point for wiring that carries analog output signals to actuators, valves, and other control elements. The board is capable of generating either a current (e.g., ) or a voltage (e.g., ) signal, depending on the specific configuration and the requirements of the connected device.

  • Current Output (mA): This type of signal is often preferred in industrial settings because it is less susceptible to electrical noise and can be transmitted over longer distances without significant signal degradation. Common ranges include or .
  • Voltage Output (V): Voltage signals are also used to control devices and are suitable for shorter distances and applications where noise is not a significant concern. A common range is .

The board’s design ensures high precision and stability in the output signals, which is essential for maintaining accurate and reliable process control.

Functional Role in a System

Within a GE Mark VIe system, the 369B1871G0007 is the physical manifestation of the control logic. The controller, having processed inputs and executed its control algorithms, sends digital commands to the I/O pack. The I/O pack then directs the terminal board to generate the appropriate analog output signal. For example, if the system needs to open a valve to a specific position, the controller will send a command that results in the terminal board outputting a precise current or voltage signal that corresponds to that position. This output signal drives the valve actuator, thereby controlling the process in the field.

Common Applications

This terminal board is critical for applications that require the control system to actively manage and manipulate a process. Its applications include:

  • Flow Control: Modulating the position of a valve to control the flow of a fluid or gas.
  • Motor Speed Control: Sending a signal to a Variable Frequency Drive (VFD) to adjust the speed of a motor.
  • Actuator Positioning: Controlling the position of a pneumatic or hydraulic actuator.
  • Process Regulation: Regulating other process variables like pressure or level by adjusting a final control element.
