Series 90-30 IC693ADC311C Alphanumeric Display | GE

Product Overview

The GE Fanuc IC693ADC311C is an Alphanumeric Display Control (ADC) module designed to provide a localized operator interface for the Series 90-30 PLC system. Featuring a clear 4-line by 20-character LCD, this module allows for real-time monitoring and adjustment of PLC variables directly from the control cabinet. With its integrated 80C188 microprocessor and 64KB memory buffer, the IC693ADC311C delivers a high-performance HMI solution that supports sophisticated menu structures, including pull-down and pop-up windows, without taxing the main PLC CPU.

Technical Specifications

Core Technical Advantages

Standalone Intelligent Processing

Equipped with its own 8MHz 80C188 microprocessor, the IC693ADC311C handles display refreshes and serial communication independently. This distributed processing ensures that adding an operator interface does not slow down the PLC's logic scan time, maintaining optimal system performance.

Simplified Configuration

The "C" revision of this module features complete software configuration. There are no complex jumpers or DIP switches to set; all setup parameters are managed through the PLC programming software, streamlining installation and reducing the potential for hardware setup errors.

Interactive Operator Interface

Beyond just a display, the module supports up to 15 user-definable screen inputs. This allows maintenance personnel to clear faults, force I/O, or change setpoints directly via the front panel, significantly improving troubleshooting efficiency on the plant floor.

Installation & Maintenance

• Port Connectivity: Communication is handled via a single 15-pin D-sub connector on the front panel, facilitating easy connection to external devices or serial printers.
• System Reset: A dedicated front-panel pushbutton allows for manual module reset without cycling power to the entire PLC rack.
• Durability: With an MTBF of 50,000 hours and a rugged storage temperature range of -40°C to 85°C, this module is built for long-term industrial reliability.

Engineering Advantages

The IC693ADC311C provides a cost-effective alternative to full-sized HMI panels for simple monitoring tasks. Its lightweight design of approximately 0.45 kg (1.0 lbs) makes it ideal for compact or high-density control cabinets. The high-accuracy real-time clock (±2 ppm) ensures that any time-stamped alarm logs captured by the module remain precise over extended periods of operation.

Technical FAQs

Q1: Can I connect a serial printer to the IC693ADC311C?
A1: Yes, the dual RS-232 ports allow the module to send alphanumeric data to a serial printer for hard-copy logging of alarms or process reports.

Q2: Does this module require a specific slot in the Series 90-30 rack?
A2: The ADC module can be placed in any standard I/O slot in a Series 90-30 baseplate, though it is commonly placed near the CPU for easy operator access.

Q3: Is the display backlit for low-light environments?
A3: Yes, the 4x20 character LCD includes a backlight to ensure readability in all industrial lighting conditions.
