Product Brief Description
The GE 369B1867G5002 (BAI21) is an Analog Input Terminal Board designed for industrial control systems within the GE Mark VIe platform. Unlike boards for general-purpose current and voltage signals, this board is specifically engineered to handle temperature measurement signals from thermocouples (TC) and Resistance Temperature Detectors (RTD). It provides a 16-channel interface for monitoring a wide range of temperature-related process variables.
Detailed Product Description
The 369B1867G5002 BAI21 is a critical component for distributed control systems using the GE Mark VIe series, particularly in applications where temperature is a key process variable. It serves as a termination board for temperature sensors, supporting two main types of signals:
- Thermocouple (TC): A sensor that measures temperature by creating a voltage at the junction of two different metals. The board provides the necessary circuitry for cold-junction compensation to ensure accurate readings.
- Resistance Temperature Detector (RTD): A sensor that measures temperature by correlating resistance with temperature. The board is configured to work with these resistance-based inputs.
This board accepts inputs from up to 16 separate channels (16CHs). It is designed with noise suppression circuitry to condition and protect these sensitive temperature signals, ensuring they are accurately converted into a digital format that the controller can process.
