IC670MDL930 GE Fanuc Field Control 8 Point Relay Module

Product Overview

The GE Fanuc IC670MDL930 is an 8-point individually isolated discrete relay output module belonging to the Field Control I/O system. Engineered for high-density, reliable switching in industrial automation and process control architectures, this module provides flexible AC/DC load driving for field devices such as solenoids, motor starters, indicator lights, and actuators.

Featuring a total of eight channels organized into six (6) Form A (Normally Open) contacts and two (2) Form C (SPDT / Normally Open & Normally Closed) contacts, the IC670MDL930 delivers channel-to-channel isolation with built-in RC snubber transient protection (R=47.5 Ω, C=0.022 µF). With a compact design weighing approximately 0.30 kg (0.66 lbs), it operable across 5–30 V DC, 31–125 V DC, and 5–265 V AC, supporting up to 2.0 A continuous load per channel (16 A maximum per module) while drawing a maximum of 313 mA from the Bus Interface Unit (BIU) logic supply.

Core Technical Advantages

• Individual Channel Isolation: Each output contact is independently isolated (250 VAC continuous, 1500 VAC for 1 min), preventing ground loops and protecting logic-side electronics.
• Mixed Contact Configuration: Integrates six Form A (N.O.) and two Form C (N.O./N.C.) silver-alloy contacts for versatile logic and safety circuit wiring.
• Integrated RC Snubber Suppression: Built-in snubber networks across contacts mitigate high-frequency voltage spikes caused by inductive load switching without external components.
• Comprehensive Diagnostic LEDs: Features channel-level status LEDs alongside power indicators to simplify field troubleshooting and signal verification.

Technical Specifications

Installation & Wiring Guidelines

• Field Base Mounting: Snap the IC670MDL930 module onto the matching Field Control terminal base, ensuring backplane connectors seal firmly to enable BIU power and data flow.
• External Power Distribution: Connect an external AC or DC field power source to drive loads connected through relay contacts. Ensure proper external fusing since the module does not contain internal fuses.
• Inductive Load Protection: While built-in RC snubbers suppress standard noise transients, high-inductance DC loads should utilize secondary flyback diodes installed directly across the load terminals.

Technical FAQs

Q1: What are the current rating limits for DC loads on the GE Fanuc IC670MDL930?
A1: Each contact supports 2.0 A for low-voltage DC (5 to 30 V DC), but drops to 0.2 A max for high-voltage DC applications (31 to 125 V DC).

Q2: Does the IC670MDL930 module provide individual channel isolation?
A2: Yes, all 8 channels are individually isolated up to 250 VAC continuous (1500 VAC for 1 minute) between groups, logic, and frame ground.

Q3: What power does the module draw from the Field Control BIU backplane?
A3: The module draws up to 313 mA from the Bus Interface Unit (BIU) power supply to energize the relay coils.
