GE IC697MDL340 Discrete Output Module

The GE IC697MDL340, also cataloged as the IC697MDL340 Discrete Output Module, operates as a dedicated hardware component for AC load switching and output signal execution within Series 90-70 PLC systems. The module provides 16 discrete 120 VAC output channels arranged in four isolated groups, allowing direct control of contactors, solenoids, motor starters, and indicator devices through the Series 90-70 backplane architecture.

Hardware Specifications

Profinet and Backplane I/O Architecture Considerations

Within the Series 90-70 PLC platform, the IC697MDL340 exchanges output state information through the rack backplane while maintaining field-side power switching through isolated output groups. The four-group architecture distributes output loading and fault containment, allowing a fuse event within one group to remain localized without directly affecting adjacent groups.

The module supports high inrush current loads commonly associated with electromechanical devices. Mechanical keying prevents installation of an incorrect module type into a configured slot, reducing maintenance-related replacement errors. Output allocation is performed through controller configuration rather than physical switches, simplifying system expansion and maintenance activities.

Frequently Asked Questions

Q: How are the outputs organized on the IC697MDL340? A: The module contains 16 outputs divided into four electrically isolated groups, with four output channels assigned to each group.

Q: What overload protection is provided? A: Each output group is protected by an independent 10 A fuse. Fuse status indication is available through dedicated front-panel LEDs.

Q: Can the module drive inductive loads such as contactors and solenoids? A: Yes. The module is designed for applications involving inductive and high inrush current loads including motor starters, contactors, and solenoid-operated devices.

Field Installation Guidelines

• Verify that the connected field devices are rated for 120 VAC operation before energizing output circuits.
• Maintain separation between output wiring and low-level signal cables to minimize electromagnetic coupling.
• Confirm proper fuse ratings and replacement procedures before commissioning the system.
• Inspect terminal torque according to site wiring standards and periodically verify connection integrity.
• Use suppression devices where required by plant standards when controlling inductive loads to reduce switching transients.
• Verify module keying configuration before replacement to prevent installation of incompatible hardware.
