I/O modules

The GE IC693NIU004 Ethernet remote I/O interface connects field devices to a control network. This unit weighs 0.42 kg and measures 13.5 cm x 9.5 cm x 3.8 cm. It provides one Ethernet port and one expansion bus connector. The module contains one communication processor, one Ethernet controller, and 2 MB of buffer memory. For energy storage, it includes one 220µF tantalum capacitor. Consequently, the GE IC693NIU004 maintains network configuration during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the GE IC693NIU004. Use this data for your system integration planning.

Ethernet Communication Features

The GE IC693NIU004 supports SRTP, Modbus TCP, and EGD protocols. Therefore, this interface works with various GE and third-party controllers. The Ethernet port auto-negotiates 10 or 100 Mbps speeds for flexible network integration. Consequently, you can connect this module to existing plant networks without changes. The communication processor handles all protocol translation tasks independently.

Remote I/O Capacity

This interface supports up to 256 digital I/O points per remote station. Additionally, it handles up to 64 analog I/O points simultaneously. Hence, the GE IC693NIU004 suits medium-sized distributed control applications. A single master controller can communicate with up to 16 remote stations. Thus, you can build a large distributed I/O network using multiple modules.

Performance and Buffer Memory

The 2 MB buffer memory stores I/O data and communication packets. This buffer prevents data loss during network congestion. The typical response time ranges from 2 to 5 milliseconds for most operations. Therefore, the GE IC693NIU004 provides real-time control performance for remote I/O. The module handles up to 1000 transactions per second without dropping packets.

Power and Energy Storage

The GE IC693NIU004 draws 280 mA from the 5V DC backplane supply. Hence, its total power consumption equals just 1.4W. The 220µF tantalum capacitor provides 15 milliseconds of hold-up time. This short backup protects network configuration during minor voltage sags. Furthermore, the module generates very little heat during operation.

Installation and Connectivity

You can mount the GE IC693NIU004 into any Series 90-30 I/O slot. The module occupies one slot in the backplane chassis. The Ethernet port accepts standard RJ45 patch cables up to 100 meters. Use shielded CAT5e or CAT6 cables for reliable communication. The expansion bus connector links to additional I/O modules in the same rack. The GE IC693NIU004 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This Ethernet remote I/O interface operates reliably from 0°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the GE IC693NIU004 suits most industrial control cabinets perfectly.
