GE IC693NIU004-FD Series 90-30 Network Interface Unit
Product Overview
The GE IC693NIU004-FD is a specialized Network Interface Unit (NIU) designed for GE’s Series 90-30 PLC system, serving as a critical bridge for communication between the PLC and industrial networks. It enables data exchange between the PLC’s CPU (such as the IC693CPU374) and external devices or systems, supporting protocols like Genius Bus and SNP (Series 90 Protocol), which are essential for integrating distributed control components.
As part of the Series 90-30 ecosystem, the IC693NIU004-FD fits into standard racks like the IC693CHS397, working seamlessly with power supplies such as the IC693PWR330 and I/O modules like the IC693MDL740K. Its primary role is to manage data flow between the PLC and remote I/O racks, HMIs, or SCADA systems, ensuring real-time information sharing in industrial settings.
Built for rugged reliability, the GE IC693NIU004-FD operates in temperatures from 0°C to 60°C and resists dust, vibrations, and electrical noise—common in factories, power plants, and water treatment facilities. Its compact design (110mm × 64mm × 30mm) and simple installation make it easy to integrate into existing systems, while LED indicators simplify troubleshooting by showing network status and power levels.

Main features and advantages
Robust network connectivity: The IC693NIU004-FD supports Genius Bus and SNP protocols, enabling seamless communication between the Series 90-30 PLC and remote devices. This is key for integrating distributed control components—like I/O racks in different parts of a factory—into a single system.
Industrial-grade durability: Built to handle temperatures from 0°C to 60°C, dust, and vibrations, the IC693NIU004-FD operates reliably in harsh environments. Its 1500V AC isolation protects against electrical noise from motors or welders, ensuring data integrity.
Easy integration: The module fits into standard Series 90-30 racks (such as the IC693CHS397) without adapters, making installation quick. It connects to the PLC’s backplane for power and data, reducing wiring complexity.
Clear status monitoring: LED indicators on the front panel show power, network activity, and errors (e.g., a failed connection). This allows technicians to troubleshoot issues—like a loose cable—without opening the control cabinet.
Scalable for growing systems: The IC693NIU004-FD can manage multiple remote I/O racks, making it suitable for expanding operations. Whether controlling a single production line or a large factory, it adapts to changing needs without replacing the entire network.

Installation and maintenance
Pre-installation preparations: Power off the Series 90-30 rack (e.g., IC693CHS397) before installing the IC693NIU004-FD. Check that the rack has an open slot and that the power supply (IC693PWR330) provides 5V DC and 24V DC. Inspect the module for damage, ensuring connectors are clean. Use a screwdriver to secure the module in the rack, and connect the Genius Bus cable to the 8-pin port.
Maintenance suggestions: Inspect the IC693NIU004-FD monthly. Check for loose connections and wipe dust from the front panel with a dry cloth. Monitor LED indicators—steady power and network lights mean normal operation; flashing lights may signal a protocol mismatch or cable issue. Every three months, test communication by sending a test signal from the PLC to a remote device, ensuring data flows correctly. Replace the module if errors persist after checking connections.
Application fields
The GE IC693NIU004-FD is widely used in industries requiring distributed control:
In automotive factories, it connects PLCs on the assembly line to remote I/O racks monitoring robotic arms. The IC693NIU004-FD relays data like arm positions to the main CPU (IC693CPU374), ensuring synchronized movement and reducing production delays.
In water treatment plants, it links pump station PLCs to a central SCADA system. The module transmits flow rates and valve statuses, allowing operators to adjust settings remotely and prevent overflows.
In food processing facilities, it integrates packaging line PLCs with quality control systems. Data from sensors (via IC693MDL740K) is sent through the IC693NIU004-FD to HMIs, alerting workers if package weights are incorrect.
In medium-sized manufacturing plants, it connects multiple production lines to a central control room. This allows managers to track output across all lines in real time, optimizing efficiency and reducing downtime.
