IC693MDL930 GE Fanuc Series 90-30 8-Point Relay Output Module

Relay Switching Architecture | Product Overview

The GE Fanuc IC693MDL930 is an eight-point relay output module for the Series 90-30 PLC platform.

It provides eight individually isolated Form A relay contacts. Each contact operates as a normally open (N.O.) switching output.

The module supports AC and DC load switching across specified voltage ranges. Each output handles up to 4 A resistive current or 2 A pilot duty current.

Individual channel isolation allows different output circuits to operate at different field voltages. This configuration suits industrial applications requiring flexible load distribution.

Its single-slot design integrates into compatible Series 90-30 PLC racks. Eight channel LEDs provide local output status indication for maintenance and troubleshooting.

Technical Specifications | Hardware & Electrical Data

Contact Design | Eight Independent Switching Channels

The IC693MDL930 uses eight individual Form A relay contacts. Each channel provides a normally open switching path.

• Independent Outputs: Each relay controls its own field load.
• Electrical Separation: Individual isolation separates output channels from one another.
• AC/DC Switching: Supports specified low-voltage DC and AC applications.
• Normally Open Contacts: Contacts close when the corresponding relay energizes.
• Local Indication: Individual LEDs help technicians identify output status.
• External Load Power: User-supplied field power operates connected devices.

Each output has its own common terminal. This arrangement supports separate field circuits without requiring one shared output voltage across all channels.

Load Selection | Electrical Switching Limits

Important Load Considerations:

• Do not exceed the rated current of an individual contact.
• Observe the 20 A total module limit for UL installations.
• Evaluate motor starting current before selecting relay outputs.
• Use suitable suppression circuits for inductive loads.
• Check contact switching frequency against the application's operating cycle.

The specified 5 A inrush figure requires consideration alongside the continuous contact ratings. Confirm the applicable load category and transient limits before switching high-inrush equipment.

Isolation & Protection | Field Circuit Design

The module provides electrical isolation between its field and logic sides. It also isolates individual output groups.

• Field-to-Logic Isolation: 1500 V.
• Output Group Isolation: 500 V between groups.
• Channel Arrangement: Individually isolated relay outputs.
• Fuse Protection: No onboard output fuses.
• Field Supply: External power supplies must energize connected loads.

Individual isolation helps engineers connect compatible loads with different field voltages. It does not replace external overcurrent protection or proper circuit design.

Engineering Recommendation: Provide suitable external branch protection for field circuits. Select protective devices according to the connected load and wiring capacity.

PLC Rack Installation | Integration Procedure

1. Verify the Part Number: Confirm IC693MDL930 against the existing hardware documentation.
2. Check Rack Compatibility: Identify the compatible Series 90-30 rack configuration.
3. Confirm Slot Availability: Reserve one slot for the module.
4. Isolate Power: Follow the PLC manufacturer's electrical safety procedures.
5. Inspect the Backplane: Check the slot connector for contamination or physical damage.
6. Install the Module: Seat the module securely in the designated position.
7. Connect Field Wiring: Follow the correct terminal assignments for each output.
8. Verify External Supplies: Check field voltage and branch protection.
9. Configure PLC Logic: Assign output addresses according to the project configuration.
10. Perform Functional Tests: Test each channel with its intended load.

The module supports installation in compatible 5-slot and 10-slot Series 90-30 backplanes. Verify the exact rack and system configuration before installation.

Commissioning | Practical Diagnostic Workflow

Use a channel-by-channel test to verify output operation before returning the system to service.

Inductive Load Management | Relay Contact Maintenance

Solenoids, contactor coils, and motor starter circuits can generate transient voltage during switching.

These transients can accelerate relay contact wear when engineers omit suitable suppression.

• DC Inductive Loads: Consider correctly rated flyback suppression.
• AC Inductive Loads: Evaluate suitable RC snubbers or approved surge suppression.
• Contact Wear: Inspect for excessive arcing or switching deterioration.
• Switching Frequency: Respect the specified 20 cycles per minute.
• Load Assessment: Review starting current and electrical duty before commissioning.

Suitable suppression can improve relay contact service life. Select suppression components according to the actual load and switching circuit.

System Compatibility | Application Guidance

The IC693MDL930 belongs to the GE Fanuc Series 90-30 discrete output family.

Typical application categories include:

• Motor Starters: Switching compatible starter control circuits.
• Solenoid Valves: Controlling suitable electromagnetic actuators.
• Indicating Lamps: Switching industrial status indicators.
• Auxiliary Relays: Operating compatible external relay circuits.
• Distributed I/O: Supporting suitable remote or distributed output arrangements.

The supplied product information also identifies RX3i and RX7i distributed I/O applications. However, compatibility depends on the specific interface, adapter, rack architecture, and system configuration.

Do not assume direct installation into every RX3i or RX7i rack. Verify the required distributed I/O hardware and integration documentation first.

Technical Verification | Important Selection Limits

• Output Type: Relay contacts, not transistor switching.
• Switching Speed: Maximum 15 ms response in either direction.
• Isolation: 1500 V field-to-logic and 500 V between output groups.
• Field Protection: External fuses or circuit protection require separate provision.
• Temperature: Specified operating range is 0°C to 50°C.
• Inductive Loads: Require appropriate suppression and load assessment.

Certification Note: The 20 A total module rating is specified for UL installations. Confirm applicable module certification and installation requirements through the manufacturer's documentation.

Frequently Asked Questions

Q1: Can the IC693MDL930 switch a load continuously throughout a production shift?

It can operate in continuous industrial applications when the load remains within its electrical ratings. However, relay contacts have finite electrical life. Engineers should evaluate switching frequency, load type, and contact wear when designing long-running applications.

Q2: Why might an output LED illuminate while the connected device remains inactive?

The LED indicates the output's commanded or relay operating status. It does not independently confirm field power delivery. Check the external supply, terminal wiring, contact continuity, and connected load before replacing the module.

Q3: Can all eight relay outputs switch different voltages simultaneously?

The individually isolated output arrangement supports separate field circuits. Engineers must still respect the voltage, current, isolation, and total module limits. Review the wiring diagram before combining AC and DC circuits in one installation.

Q4: What causes premature relay contact failure in solenoid and contactor applications?

Inductive switching can generate electrical arcs and transient voltages. These effects accelerate contact erosion. Proper suppression, correct load selection, and suitable switching frequency help reduce premature wear.

Q5: How should engineers evaluate this module when replacing an existing output assembly?

Compare the output contact form, channel isolation, field voltage, load current, terminal arrangement, and PLC address mapping. Also inspect the original wiring for external fuses and suppression components. A matching part number alone does not verify the complete field circuit.
