GE IC693MDL230B AC Digital Input Module

Product Dimensions：

The GE Fanuc IC693MDL230B is a 120 Volt AC, 0.5 Amp, 8-Point Isolated Discrete Output Module designed for use with the Series 90-30 Programmable Logic Controller (PLC) system.

Product Detailed Description

The IC693MDL230B provides eight independent, isolated output channels for controlling AC loads such as solenoids, motor starters, indicators, and small relays. The defining characteristic of this module is channel-to-channel isolation. Unlike standard output modules that share a common return, each of the 8 channels on this module has its own isolated common return terminal. This allows the module to control loads powered by different AC power sources or phases on a single card.

Technical Parameters

Product Advantages

• True Electrical Isolation: Because each point is isolated from the others, you can intermix different phases of AC power or entirely different AC power grids within the same physical module without risk of cross-talk or short circuits.
• Individual Fusing: The module is designed to safeguard internal components; however, the isolation helps ensure that a catastrophic fault on one field circuit does not propagate and damage adjacent channels.
• Clear Diagnostics: Features 8 top-mounted LED indicators (arranged in a single row) that display the ON/OFF status of each logic side output point to simplify troubleshooting.
• Reliable Switching: Uses solid-state components (typically Triacs) optimized for AC voltage switching, ensuring a longer operational lifespan compared to mechanical relay contacts.

Important Considerations & Precautions

• Minimum Load Requirement: The module requires a minimum load of 10 mA to function properly. If you connect a high-impedance device (like a small LED indicator or a sensitive digital input of another device), the leakage current may prevent the load from turning off. A loading resistor must be added in parallel if this occurs.
• AC Power Only: This module uses Triacs as switching elements, which rely on the zero-crossing of AC current to turn off. Do not connect DC loads to this module, as the outputs will latch “ON” permanently until power is cut.
• Total Module Current: While each point can handle up to 0.5 A, ensure the sum of all simultaneous outputs does not exceed the maximum module rating of 4.0 A at your specific operating temperature.
• Wiring Orientation: Always refer to the faceplate wiring diagram. Because each channel has its own pair of terminals (Output and Return), incorrect cross-wiring can inadvertently bypass the isolation.

Product Applications

The IC693MDL230B is widely utilized in legacy industrial and infrastructure setups:

• Multi-Phase Systems: Controlling discrete field devices that operate on different legs of a 3-phase AC distribution system.
• Substation Control Panels: Interfacing with auxiliary equipment driven by distinct, isolated utility power supplies.
• Water & Wastewater Treatment: Actuating 120V AC chemical feed pumps, solenoid-operated valves, and status pilot lights.
• Process Automation: Managing independent pilot circuits inside MCC (Motor Control Center) buckets where separate control transformers are utilized.
