GE IC697VDD100

Description

Product Overview and Description

The GE IC697VDD100 is a critical discrete output module from the renowned GE Fanuc Series 90-70 PLC family. This 100-125 VDC sourcing output module serves as the vital interface between the PLC’s logic processor and real-world DC actuation devices, enabling precise control in industrial environments. Designed for high-density applications, the GE IC697VDD100 module allows for the efficient control of numerous devices like solenoid valves, contactor coils, indicator lamps, and motor starters from a single PLC rack slot. Engineered for reliability in demanding settings, the GE IC697VDD100 incorporates robust isolation and protection features to ensure system longevity. It represents a core component for engineers building or maintaining automation systems based on the versatile Series 90-70 platform, making the GE IC697VDD100 an indispensable spare part for sustaining operational continuity.

Advantages and Distinctive Features

The GE IC697VDD100 offers several key advantages for system designers and maintenance teams. Its primary strength is high point density, which maximizes control capability per rack slot and reduces overall hardware costs for large-scale applications. A standout safety and reliability feature is the inclusion of individually fused outputs on the GE IC697VDD100; this design prevents a single-point fault from disabling the entire module, thereby increasing system availability and simplifying troubleshooting. The module provides robust optical isolation, protecting the sensitive PLC backplane from damaging voltage transients and noise commonly found on industrial DC power circuits. The reliable construction and wide operational voltage range (100-125 VDC) of the GE IC697VDD100 ensure compatibility with common industrial control voltages.

Application Cases in Key Fields

• Material Handling & Conveyor Systems: Controlling the solenoid valves of pneumatic diverters, gates, and brakes across extensive warehouse automation lines. The 32-point capacity of the GE IC697VDD100 is ideal for managing multiple zones from a centralized controller.
• Automotive Manufacturing: Actuating welding gun clamps, fixture locks, and tooling actuators in body-in-white assembly stations, where reliable DC control is paramount for cycle time and safety.
• Water/Wastewater Treatment: Operating DC-powered pilot valves for large diaphragm control valves, chemical dosing pumps, and filter backwash sequences, where the module’s isolation withstands harsh electrical environments.
• Machine Tool Control: Managing tool changers, coolant pumps, chuck clamps, and tower light indicators on CNC machines and machining centers.

Comparison with Competing Products

Compared to generic or low-cost DC output modules, the GE IC697VDD100 stands out for its industrial-grade construction, individual point fusing, and high isolation ratings. Competing modules in other PLC families (e.g., Siemens Simatic S5 or Allen-Bradley PLC-5) may offer similar functionality but are not interchangeable due to proprietary backplanes and configuration software. Within the GE Series 90-70 family itself, the GE IC697VDD100 is distinct from lower-voltage DC modules (like 24VDC) or relay output modules, offering a direct, fast, and reliable interface for 110VDC control circuits without the moving parts and slower switching times of relays.

Selection Suggestions and Precautions

Selection Suggestions:

1. Select the GE IC697VDD100 specifically for expanding or replacing failed modules in an existing GE Series 90-70 PLC system.
2. Choose this module when your field devices (e.g., solenoid valves) require a 100-125 VDC control signal and a sourcing configuration.
3. It is the optimal choice for applications demanding high reliability and where individual point protection to simplify maintenance is a priority.

Important Precautions:

1. Voltage Compatibility: Confirm your field power supply is a stable 100-125 VDC. Applying voltage outside this range can damage the module.
2. Sourcing Configuration: Ensure your field devices are wired correctly for a sourcing output. The module supplies positive voltage; the field device must be connected to the common (negative) line.
3. Heat Dissipation: Calculate the total heat dissipation based on the current draw of all simultaneously active points, especially in high-density racks, to ensure the PLC enclosure cooling is adequate.
4. Fuse Replacement: Always replace blown fuses with the specified rating. Using a higher-amp fuse can lead to damage of the output transistor and potentially the field device.
5. Legacy System Awareness: The Series 90-70 is a mature platform. Ensure you have compatible configuration hardware (Logicmaster 90) or software (Proficy Machine Edition) for setup and troubleshooting. Verify source for genuine or reliable refurbished units.
