The GE IC670MDL930 is a discrete relay output module engineered by GE Fanuc, designed to support industrial automation tasks with dependable switching capabilities. As part of the Field Control series, this module provides eight isolated relay outputs tailored for both normally-open and normally-closed operations. Thanks to its robust design and versatile voltage handling, it has long been a staple in control systems across various industrial sectors.
The IC670MDL930 module stands out for offering six Form A (normally open) and two Form C (normally open or closed) relay contacts. These are ideal for controlling devices with a wide range of voltage requirements. It supports both AC and DC operations — specifically 5/24/125V DC and 120/240V AC — and has a maximum resistive load current of 16 amps per module. The unit includes snubber protection to mitigate high-frequency noise and ensure smooth switching.
Key specs include:
• Voltage Range: 0–130V DC / 0–265V AC
• Frequency Range: 47–63 Hz
• Contact Type: Silver alloy for durability
• Switching Frequency: 20 cycles/minute
• Mechanical Life: Up to 20 million operations
• Electrical Life: 100,000 operations at rated load
Thanks to its isolated design and dual contact types, the IC670MDL930 is perfect for a variety of industrial control applications. It's commonly found in systems that demand high-current switching, such as:
• Factory automation
• Process control systems
• Motor control
• HVAC systems
• Distributed I/O systems
Its compatibility with a range of voltages and currents makes it a flexible option for engineers building or maintaining legacy systems.
Installing the IC670MDL930 is straightforward for trained technicians. The module features individual channel LEDs for real-time output status and a power LED for system health monitoring. Its fixed coil and moving armature relay design ensures reliable performance. The module draws 313 mA from the backplane and is designed without a fuse, relying instead on a built-in RC snubber for circuit protection.
While the IC670MDL930 doesn’t support in-module fusing, external protective measures are recommended to safeguard connected components from overloads.
The IC670MDL930 has reached "obsolete" status in GE's product lifecycle, meaning it is no longer in production. However, it is still widely used in legacy systems. Users can often source refurbished or surplus units from industrial parts suppliers, and technical support documentation remains available through third-party resources.
If you're planning an upgrade or system redesign, consider compatible modules from GE's newer I/O lines or third-party alternatives offering similar specifications.
The GE IC670MDL930 relay output module exemplifies the reliability and versatility expected from industrial-grade control components. Despite being discontinued, it continues to serve a crucial role in many older automation systems due to its robust performance and adaptable features. For engineers maintaining legacy systems, the IC670MDL930 remains a trusted and viable solution — with the caveat that future planning should consider migration paths to modern hardware.
