IC693MDL730 | GE Fanuc Series 90-30 12/24VDC 2A Positive Logic 8-Point Output Module

Product Overview

The IC693MDL730 is a robust discrete output module designed for the GE Fanuc (now Emerson) Series 90-30 PLC ecosystem. This specific unit is engineered for high-current applications, providing eight independent channels capable of switching up to 2.0 Amperes per point. Operating on a positive logic (source) configuration, it bridges the gap between low-level PLC logic and heavy-duty field actuators like large solenoids, motor starters, and hydraulic valves.

Detailed Technical Specifications

The following data represents the operational limits and electrical characteristics of the IC693MDL730 module. Note that while the lifecycle status is officially "Mature/Discontinued" by the OEM, these units remain critical for maintaining legacy 90-30 infrastructure.

Operational Constraints and Fusing

The IC693MDL730 utilizes two internal 5-Amp fuses. Each fuse protects a specific branch of four outputs. It is vital for engineers to calculate the thermal derating based on the ambient cabinet temperature. If the environment reaches 60°C, the total current per fuse must be halved to ensure hardware longevity and prevent nuisance tripping of the protection circuit.

Common Application Scenarios

• High-Inductive Loads: Driving large DC contactors or heavy-duty solenoid valves that exceed standard 0.5A output capacities.

• Legacy System Expansion: Maintaining existing Series 90-30 racks where high-density 2A sourcing is required without upgrading the entire CPU architecture.

• Safety Interlocks: Utilizing the 1500V isolation to protect the PLC logic from field-side electrical noise and surges.

Technical FAQ

What is the difference between Positive Logic and Negative Logic for this module?

The IC693MDL730 is a positive logic module, meaning it "sources" current to the load. The output terminal connects to the positive side of the device, while the other side of the device is connected to the common return.

How is the module protected against overcurrent?

The module contains two 5A fuses. Unlike some electronic short-circuit protection modules, these are physical fuses. If a sustained overcurrent occurs, the fuse will blow to protect the internal circuitry and must be replaced.

Can I use this module with 5VDC logic?

No, the operating range is strictly 12 to 24 VDC. Attempting to switch 5V loads may result in unreliable operation due to the 1.2V internal voltage drop.
