Description

IC670MDL740: Product Overview​
The GE IC670MDL740​ is a 16-point discrete output module from GE’s Field Control series, a legacy platform renowned for its modularity and reliability in industrial automation. As part of the Field Control ecosystem, it acts as a “switching interface” between the VMEbus controller and field devices (e.g., relays, solenoids), enabling precise control of industrial processes. Its primary role is to convert digital signals from the controller into physical actions (e.g., turning on a pump, activating a valve), which is critical for maintaining process stability and efficiency.
Role in Automation Systems:
Positioned as a “field output interface” in Field Control architectures, the IC670MDL740 performs two primary functions:
  1. Signal Conversion: Receives digital signals (0/24 V DC) from the VMEbus controller and converts them into high-current outputs (0.5 A per channel) to drive field devices.
  2. Device Control: Sends control commands to field actuators (e.g., relays, solenoids) to adjust industrial processes (e.g., starting a conveyor belt, stopping a pump).
Core Functionality:
  • Positive Logic Outputs: Uses sourcing (NPN) circuitry, meaning the output switches the positive side of the load circuit. This is compatible with most industrial sensors and actuators.
  • High Current Capacity: Each channel supports up to 0.5 A, allowing it to drive multiple devices (e.g., relays, solenoids) simultaneously.
  • Galvanic Isolation: Optocouplers isolate field devices from the controller, protecting sensitive electronics from voltage spikes and electromagnetic interference (EMI) in harsh industrial environments.
  • Modular Design: Fits into standard Field Control I/O racks, enabling easy expansion or replacement. The hot-swappable design minimizes downtime during maintenance.
Platform Benefits (Field Control Series):
The IC670MDL740 inherits the Field Control platform’s strengths, including:
  • Reliability: The Field Control system is the industry standard for industrial automation, with a proven track record of 24/7 operation in power plants, refineries, and manufacturing facilities worldwide.
  • Legacy Compatibility: The module is designed to work with existing Field Control components (e.g., I/O racks, controllers), reducing the cost of system upgrades.
  • Scalability: Supports expansion with additional I/O modules (e.g., analog inputs, digital inputs) to accommodate growing system demands.

Core Features & Customer Value​
1. Reliable Device Control:
The IC670MDL740’s high current capacity (0.5 A per channel) and galvanic isolation ensure reliable control of field devices, even in electrically noisy environments. For example, in a power plant, the module can reliably activate a pump relay to maintain coolant flow, preventing turbine overheating.
2. Flexible Configuration:
The 16-point design allows engineers to customize the module’s functionality for different applications. For instance, in a manufacturing plant, the module can control multiple conveyor belts or robotic arms using a single module, reducing the need for additional hardware.
3. Rugged Industrial Design:
The module’s operating temperature range (-20°C to +60°C) and compact form factor make it suitable for harsh industrial environments. Its DIN rail mounting option simplifies installation in crowded control cabinets, reducing setup time and effort.
4. Easy Integration:
Compatibility with GE Fanuc Field Control systems ensures seamless integration with existing VMEbus architectures. This minimizes downtime and effort during upgrades, allowing facilities to enhance system capabilities without replacing entire infrastructures.
