General Electric IC693ADC311 Alphanumeric Display Coprocessor

The GE IC693ADC311 Alphanumeric Display Coprocessor is a dedicated text-based operator interface module designed for the Series 90-30 PLC system. It provides a simple yet effective method for displaying process information, alarms, and operational messages directly at the control cabinet. This module is intended for users who require local, real-time feedback without the need for external HMIs or complex software.

Featuring a 2-line, 16-character alphanumeric LCD display, this coprocessor allows PLC data to be read and written interactively through user-configurable menus and keystrokes. With integrated push-button keys, plant operators can navigate menus, acknowledge alarms, or trigger basic commands, making it a cost-effective alternative to traditional HMIs for basic monitoring and control.

Technical Specifications

Product Applications

The IC693ADC311 coprocessor is tailored for environments where real-time visibility of PLC activity is required but a full-fledged HMI is unnecessary or impractical. It is ideal for:

• Factory Floor Monitoring – Enables operators to monitor machine status or process parameters without leaving the cabinet.

• Alarm Notification Systems – Displays real-time alarms and allows acknowledgement via keypad interaction.

• Simple User Input Interfaces – Accepts numeric or menu-based input from users to influence control logic.

• Remote or Compact Installations – Suitable for small enclosures or mobile skids where full screens are impractical.

• Maintenance Panels – Technicians can quickly inspect values or messages for troubleshooting.

• Educational or Training Units – Provides a visible interface for teaching PLC logic flow and human interaction.

Product Advantages

• Compact and Cost-Effective: Delivers basic display and control functions at a fraction of the cost of touch HMIs.

• Plug-and-Play Integration: Installs directly into the PLC rack, minimizing wiring and setup time.

• Customizable Display: Messages and data points are fully programmable via ladder logic or function blocks.

• Onboard Keypad: Built-in keys allow direct user input, acknowledgment, or navigation through menus.

• No External Power Needed: Powered via the backplane, reducing wiring complexity.

• Increased System Transparency: Provides immediate feedback from control processes, aiding operators and engineers.

• Robust Design: Suitable for harsh industrial conditions, certified for reliability and safety.

FAQ

1. What does the IC693ADC311 display module do?

   It provides a 2-line alphanumeric display for real-time messages, data monitoring, and basic operator interaction.

2. Can I input values through the keypad?

   Yes, the keypad allows users to input values, navigate menus, and acknowledge events.

3. Is this compatible with newer GE PLCs like RX3i?

   No, it is designed specifically for the Series 90-30 platform.

4. How is this different from a traditional HMI?

   It’s a simplified, embedded operator interface meant for basic display and input tasks, without graphics or touchscreen features.

5. Do I need additional software to program it?

   It is configured through the same logic software used for the PLC (e.g., Proficy Machine Edition).

6. What kind of messages can it show?

   You can program it to show alarms, process values, setpoints, status messages, or operator instructions.

7. Does it occupy a CPU slot?

   No, it uses a regular I/O slot in the Series 90-30 rack.

8. Can I use this in a remote I/O rack?

   It is best used in the local rack for real-time interaction and minimal latency.

9. Is there backlight support on the LCD?

   Yes, the screen includes a backlight for visibility in dim environments.

10. How is the durability for industrial use?

    It’s built with rugged industrial materials and certified for operation in harsh environments.
