GE S739DVT

Description

Product Description

GE S739DVT is a high-performance, discrete output module designed for use within the GE Fanuc Series 90-30 Programmable Logic Controller (PLC) system. This module, the GE S739DVT, provides a reliable interface for the PLC to control external devices such as solenoid valves, motor starters, indicator lights, and relays by switching higher-power loads. As a part of the versatile Series 90-30 family, the S739DVT output module is engineered for robust industrial operation, ensuring precise and reliable control signals to field actuators from the central processor. Its design prioritizes both operational integrity and ease of integration into existing control panels.

Product Parameters and Specifications

• Module Type: Discrete (Digital) Output Module.

• Series Compatibility: GE Fanuc Series 90-30 PLC.

• Number of Channels: 16 discrete output channels.

• Output Type: Typically solid-state DC outputs (e.g., transistor-based). The specific voltage is defined by the part number suffix.

• Output Voltage: Commonly 24 V DC. The exact rating must be verified by the specific “DVT” suffix code.

• Current Rating per Point: Typically 0.5 A to 2.0 A per point, with a total module current limit.

• Isolation: Optical isolation between the internal logic (PLC side) and the output switching circuits (field side) to protect the controller from electrical noise and transients.

• Status Indication: LED indicator for each output channel to show the ON/OFF state.

• Connection: Removable terminal block for easy wiring and maintenance.

• Power Consumption: Draws a specific amount of current from the +5 V DC backplane; details are provided in the technical manual.

Advantages and Features

1. High-Density Design: The GE S739DVT packs 16 output points into a single module slot, optimizing space within the Series 90-30 rack and reducing the hardware footprint of the control system.

2. Fast Switching and Reliability: Utilizing solid-state switching technology, this module offers rapid response times and a long operational lifespan with no moving parts, unlike electromechanical relays, making it ideal for high-cycle applications.

3. Enhanced System Protection: The built-in optical isolation on the S739DVT module is a critical feature that prevents voltage spikes or faults on the field side from damaging the sensitive electronics of the central CPU and other modules in the rack.

4. Easy Diagnostics and Maintenance: Individual LED status lights for every channel allow for instant visual confirmation of output commands, significantly simplifying troubleshooting and reducing downtime during commissioning or repairs.

5. Seamless Integration: As a native component of the Series 90-30 system, the module is automatically recognized by the programming software (such as Proficy Machine Edition or VersaPro), and its configuration is straightforward within the hardware configuration tree.

Application Cases in Various Fields

• Automated Manufacturing & Assembly Lines: Controlling pneumatic cylinders, clamping units, conveyor belt stops, and robotic tool changers. The GE S739DVT provides the reliable switching signals needed for sequential machine operations.

• Material Handling: Operating solenoid valves for diverters and pushers, controlling sortation systems, and managing palletizer functions in warehouses and distribution centers.

• Packaging Machinery: Activating sealing jaws, fillers, labelers, and discharge mechanisms where precise timing and reliability are paramount.

• Building Automation: Managing fan coil units, pump controls, and damper actuators in HVAC systems.

• Water/Wastewater Treatment: Controlling chemical dosing pumps, valve actuators for flow diversion, and alarm indicators.

Comparisons with Competing Products

Compared to similar discrete output modules from competitors like Siemens (for S7-300 series), Allen-Bradley (Rockwell Automation 1734/1792 for CompactLogix), or Schneider Electric (for Modicon M340), the GE S739DVT holds its primary advantage in its native integration and cost-effectiveness within the GE Series 90-30 ecosystem. The Series 90-30 platform is known for its robustness and value. While competitors may offer modules with similar point density and switching capabilities, the choice of the S739DVT is typically driven by the need for direct compatibility with an existing 90-30 base, a preference for GE programming environments, or specific project legacy requirements. It represents a mature, proven technology.

Selection Suggestions and Precautions

1. Verify Voltage and Current Ratings: The suffix “DVT” specifies the voltage (e.g., 24V DC). It is crucial to select the correct module variant that matches your field device voltage and does not exceed the current rating per point and for the entire module. Always check the load inrush currents, especially for inductive loads like solenoids.

2. Use External Protection for Inductive Loads: When switching inductive loads (relays, solenoids), always use external suppression devices like flyback diodes or varistors across the load to protect the S739DVT module’s solid-state outputs from voltage transients generated when the circuit is de-energized.

3. Confirm Backplane Power Budget: Before adding any module, calculate the total +5V DC current consumption of all modules in the rack. Ensure the CPU’s power supply or any expansion power supplies can support the additional load from the GE S739DVT.

4. Follow Proper Wiring Practices: Use correct wire gauges, secure connections on the terminal block, and adhere to separation guidelines for signal and power cables to minimize electromagnetic interference.
