The General Electric 148C6901G001 is a high-reliability single alarm module from the specialized I&C5000 (Instrumentation and Control) series. Engineered by GE’s energy and power divisions, this module is designed to monitor critical process variables in power plants and heavy industrial facilities. It serves as a dedicated watchdog, providing local visual indication and remote relay contacts when a monitored signal (such as temperature, pressure, or level) exceeds or falls below a predefined set-point.

 

Technical Description & Parameters

The 148C6901G001 is a solid-state electronic component built to withstand the electromagnetic interference (EMI) commonly found in turbine control rooms and electrical substations.

• Model Number: 148C6901G001
• Series: I&C5000 Industrial Control
• Input Signal: Typically accepts standard analog process signals (1-5V DC, 0-10V DC, or 4-20mA)
• Configuration: Single Alarm (monitors one set-point per module)
• Output: Dry relay contacts (Form C) for remote annunciation or interlocking
• Power Requirement: 24V DC or 125V DC (depending on specific backplane/rack power)
• Response Time: High-speed electronic monitoring (typically <100ms)
• Mounting: Plug-in card designed for GE I&C standard sub-racks

 

Product Datasheet Essentials

This module features high-precision potentiometers on the front panel, allowing technicians to manually calibrate the “Trip” and “Deadband” (hysteresis) levels. The “Single” designation indicates it is a one-channel device, focused on a specific critical limit. It includes a high-visibility LED indicator on the faceplate that illuminates when the alarm condition is active. The 148C6901G001 is recognized for its thermal stability, maintaining accurate set-points even in varying ambient temperatures within control cabinets.

Application Fields

The I&C5000 series is a staple in high-availability infrastructure:

• Power Generation: Monitoring bearing temperatures in steam and gas turbines.
• Nuclear Instrumentation: Specialized signal monitoring in non-safety-related control loops.
• Chemical Plants: High-level or low-pressure alarms for critical storage tanks.
• Oil & Gas: Integrated into pump station control panels for fault detection.

 

Product Usage Instructions

1. Installation: Insert the module into the designated slot of the I&C5000 rack. Ensure the rear edge connectors are properly seated before tightening any retaining screws.
2. Input Wiring: Connect the process signal leads to the corresponding terminals on the rack backplane. Ensure the signal polarity matches the module’s input requirements.
3. Calibration: Using a calibrated signal generator, simulate the desired “Trip” level. Adjust the front-panel potentiometer until the alarm LED just activates.
4. Hysteresis Adjustment: Set the “Deadband” to prevent “chattering” (rapid cycling) of the alarm if the process signal fluctuates near the set-point.
5. Functional Test: Manually trigger the alarm and verify that the output relay correctly signals the remote annunciator or SCADA system.

Common Questions & Answers (Q&A)

Q: Can this module be used for both “High” and “Low” alarm configurations? A: Yes, the 148C6901G001 can typically be configured via internal jumpers to trip on either a rising signal (High Alarm) or a falling signal (Low Alarm).

Q: Is the I&C5000 series still supported by GE? A: This is a legacy series. While new production is limited, high-quality refurbished units and expert repair services are available to maintain existing control systems without requiring a full system forklift upgrade.

Q: What is the purpose of the “G001” suffix? A: The “G” followed by a number (Group number) indicates a specific hardware revision or a particular input voltage/signal range as defined by GE’s internal engineering standards.
