Product Brief Description

The GE 369B1871G5003 BAO21 Analog Output Base is a key component of the GE Mark VIe control system. Similar to other bases, it provides the physical interface for an I/O pack. This model, designated as BAO21, offers 8 channels for analog output and supports both current (mA) and voltage (V) signals. Unlike the BAO20 model, the primary documentation available does not specify native HART communication, making it a more standard analog output solution.

Detailed Product Description

The 369B1871G5003 serves as a terminal board for an analog output I/O pack within the Mark VIe system. It is designed for mounting on a DIN rail or in a control cabinet. The base provides a robust and reliable connection between the I/O pack and the field devices that require an analog signal for control. The “BAO21” designation refers to the Base Analog Output, 8 channels.

The primary function of this base is to deliver a precise analog signal to actuators and other field instruments. The I/O pack, when installed on this base, receives digital commands from the controller and converts them into the required analog signal ( or , for example). The BAO21 model is a straightforward analog output base, ideal for applications where the enhanced diagnostics of HART communication are not required.

Functional Role in a System

Within a Mark VIe system, the 369B1871G5003 is a critical part of the output loop. The system’s controller processes control logic and sends digital output commands to the I/O pack. The I/O pack, which is secured on the BAO21 base, then generates a stable analog signal. This signal is sent to a field device, such as a control valve or a variable frequency drive, to manipulate a process variable. This base is essential for a wide range of industrial control applications.

Common Applications

The BAO21 base is well-suited for industrial applications that require standard analog control signals. Common applications include:

  • Basic Process Control: Controlling valves, pumps, and other equipment in a straightforward process loop where HART diagnostics are not a priority.
  • General-Purpose Automation: Providing analog outputs for a variety of general automation and sequencing tasks.
  • Control Upgrades: Implementing a simple and reliable analog output solution when upgrading to a Mark VIe system without needing the advanced features of a HART-enabled base.
