• Isolation: Opto-couplers provide isolation between the logic side and the field side.
• Output Groups: Four isolated groups of 8 outputs each, with individual commons.
• Connectors: Two 24-pin male connectors on the front of the module for field wiring.
• Forced OFF State: When the PLC CPU stops, all module outputs are forced to the OFF state.

3. Advantages and Features

The IC693MDL753K GE output module offers several significant advantages and features:

• High Output Density: Provides 32 output points in a single module, maximizing I/O capacity and minimizing panel space requirements.
• Versatile Voltage Range: Operates within a 12/24 VDC range, making it suitable for controlling a wide variety of DC-powered devices.
• Isolated Output Groups: The four isolated output groups enhance flexibility, allowing different loads with potentially different voltage levels or grounding configurations to be controlled independently.
• Positive Logic (Sourcing): Simplifies wiring for many common industrial control applications where devices are switched on the positive side of the power supply.
• Overload Protection: While specific overload protection mechanisms per point might vary, the current limitations per point and per common help protect the module and connected devices from excessive current draw.
• Forced OFF on CPU Stop: This safety feature ensures that all outputs are de-energized in the event of a PLC CPU fault or stop, preventing unintended operation of controlled devices.
• Reliable Interface: Opto-isolation provides electrical isolation between the PLC logic and the field devices, enhancing noise immunity and protecting the controller from field wiring issues.

4. Application Areas and Application Cases

The IC693MDL753K GE output module is widely used in various industrial automation applications where discrete DC outputs are required, including:

• Controlling Solenoid Valves: Used to actuate pneumatic or hydraulic valves in automated machinery.
• Driving Relays and Contactors: Interfaces with higher-power AC or DC circuits through relays and contactors.
• Activating Indicator Lights and Alarms: Provides signals to visual and auditory indicators for machine status or fault conditions.
• Interfacing with Motor Starters: Controls the starting and stopping of small DC motors or pilot circuits of larger motor starters.
• Packaging Machinery: Controls actuators for tasks such as sealing, filling, and conveying.

Application Case: In an automated assembly line, an IC693MDL753K GE module is used to control various 24 VDC solenoid valves that actuate pneumatic cylinders. These cylinders are responsible for clamping parts, advancing slides, and ejecting finished products. The 32 output points of the IC693MDL753K GE allow for the independent control of multiple axes of motion and sequential operations within the assembly process. The isolated output groups are utilized to manage different sections of the machine with potentially varying grounding requirements. The forced OFF state during a PLC stop ensures that all actuators are safely de-energized, preventing potential hazards during maintenance or system faults.

5. Competitor Comparison

While other manufacturers offer discrete DC output modules for their PLC systems, the IC693MDL753K GE is specifically designed for seamless integration with the GE Fanuc Series 90-30 PLC platform. Compared to generic output modules, the IC693MDL753K GE provides guaranteed compatibility and leverages the specific architecture and communication protocols of the Series 90-30 system. While a third-party 32-point DC output module might offer similar electrical specifications, it may require additional configuration and may not have the same level of integration and tested compatibility within a GE Fanuc system. The specific features like isolated output groups and the forced OFF state are also tailored to the safety and operational requirements of industrial applications within the GE Fanuc ecosystem.

6. Selection Advice

When selecting a discrete DC output module for a GE Fanuc Series 90-30 PLC, such as the IC693MDL753K GE, consider the following:

• Voltage and Current Requirements: Ensure the module’s voltage and current ratings are suitable for the output devices you need to control. Verify that the maximum current per point and per common is sufficient for your loads.
• Number of Output Points: Choose a module with an adequate number of output points for your current and future application needs.
• Logic Type (Sourcing/Sinking): Select the appropriate logic type (positive/sourcing in the case of IC693MDL753K GE) to match the requirements of your field devices.
• Isolation Requirements: Consider whether isolated output groups are necessary for your application to handle different power supplies or grounding schemes. The IC693MDL753K GE provides this flexibility.
• Safety Features: Evaluate the importance of safety features like the forced OFF state during a CPU stop for your application.
• Compatibility: Always ensure that the selected output module is compatible with your specific GE Fanuc Series 90-30 PLC CPU and baseplate.

7. Precautions

When installing and using the IC693MDL753K GE output module, observe the following precautions:

• Disconnect Power: Always disconnect power from the PLC system before installing or removing any I/O modules.
• Proper Wiring: Follow the wiring diagrams provided in the GE Fanuc documentation carefully. Ensure that all connections are secure and made to the correct terminals. Pay attention to the common connections for each output group.
• Current Limits: Do not exceed the maximum current ratings per output point (0.5 Amps) and per common (3.0 Amps) to prevent damage to the module and connected devices.
• External Protection: For inductive loads, such as solenoid valves or relays, it is recommended to use appropriate surge suppression devices (e.g., diodes or RC snubbers) to protect the output module from voltage transients.
• ESD Protection: Handle the module with appropriate electrostatic discharge (ESD) protection during installation and maintenance.
• Environmental Limits: Ensure that the module is operated within its specified temperature and humidity ranges.
• Regular Inspection: Periodically inspect wiring and connections for any signs of damage or loosening.
