Product Details

IC695CMM004LT Product Description

The GE IC695CMM004LT is a 4-port serial communications module engineered for the GE PACSystems RX3i platform, delivering robust multi-protocol serial connectivity within distributed industrial control architectures. Designed to operate seamlessly within the RX3i universal backplane ecosystem, this module addresses the critical need for reliable, high-density serial communication across control layers — from field device integration to supervisory data exchange. Whether deployed in a greenfield automation project or integrated into an existing legacy migration strategy, the IC695CMM004LT provides the architectural consistency and signal stability that modern industrial environments demand.

At NANKMOS, every IC695CMM004LT unit is sourced through verified supply channels, subjected to pre-shipment functional testing, and backed by a 12-Month Warranty — ensuring your control architecture investment is protected from commissioning through long-term operation.

The IC695CMM004LT does not operate in isolation — its true value is realized when viewed as a functional node within a fully integrated PACSystems RX3i control architecture. In a typical deployment, the IC695CPE302 or IC695CPE305 CPU module serves as the central processing unit, executing ladder logic and managing all backplane communications. The IC695CMM004LT occupies one or more I/O slots on the IC695CHS012 12-slot universal backplane, sharing the high-speed backplane bus with analog and digital I/O modules such as the IC695ALG608 (8-channel analog input) and IC695MDL654 (16-point discrete output).

For power distribution, the IC695PSA040 or IC695PSD040 power supply modules provide stable 24 VDC backplane power, ensuring that the CMM004LT and co-resident modules operate within specified electrical tolerances even under full I/O load. In architectures requiring Ethernet-based supervisory connectivity alongside serial field device integration, the IC695ETM001 Ethernet communications module can be installed in an adjacent slot, enabling simultaneous SRTP, Modbus TCP, and EGD protocol support — while the IC695CMM004LT handles RS-485 Modbus RTU polling of legacy field instruments, drives, and meters.

For applications demanding high availability, the RX3i platform supports CPU redundancy configurations using paired IC695CPE330 controllers with the IC695RMX128 redundancy memory exchange module. In such architectures, the IC695CMM004LT's port-level diagnostics and fault logging capabilities contribute directly to system-wide health monitoring, allowing the redundancy manager to assess communications layer integrity during switchover events. Additionally, in distributed I/O topologies, the IC695PBM300 PROFIBUS master module or IC695EIS001 PROFINET scanner can coexist on the same backplane, enabling multi-network architectures where serial, PROFIBUS, and PROFINET field devices are managed from a single RX3i rack — reducing panel footprint and simplifying engineering integration.

HMI connectivity is typically achieved through dedicated serial or Ethernet links from the IC695CMM004LT's RS-232 ports to operator panels such as the QuickPanel+ series, enabling real-time process visualization without additional communication gateways. This tight Contextual Integration between the communications module, CPU, I/O subsystem, and HMI layer is a defining characteristic of the PACSystems RX3i platform's modular architecture philosophy.

Manufacturing & Discrete Automation: In automotive assembly lines and general manufacturing facilities, the IC695CMM004LT enables serial communication with barcode scanners, vision systems, servo drives, and legacy PLCs via RS-232 and RS-485 interfaces. Its multi-port design allows a single module to simultaneously manage multiple field device classes, reducing slot consumption and simplifying wiring in compact control cabinets.

Power Generation & Utilities: In power plant auxiliary systems and substation automation, the module's RS-485 Modbus RTU capability supports integration with protective relays, energy meters, and UPS systems. The IC695CMM004LT's industrial-grade operating temperature range and backplane-powered design make it well-suited for the demanding electrical environments found in power distribution control rooms.

Oil, Gas & Petrochemical: Process control systems in refineries and pipeline monitoring stations frequently rely on serial communications for SCADA integration with flow computers, gas analyzers, and pressure transmitters. The IC695CMM004LT's SNP and Modbus RTU protocol support enables direct integration with these instruments, while its diagnostic capabilities support the rigorous maintenance documentation requirements of process safety management (PSM) programs.

Water & Wastewater Treatment: Municipal water treatment facilities use the IC695CMM004LT to communicate with chemical dosing pumps, flow meters, and remote I/O panels over RS-485 networks. The module's ability to support multiple serial protocols on independent ports allows a single RX3i rack to serve as a multi-function communications hub for an entire treatment plant process area.

Mining, Metallurgy & Heavy Industry: In ore processing and smelting operations, where vibration, dust, and temperature extremes challenge conventional electronics, the IC695CMM004LT's robust industrial design and backplane integration provide the reliability required for continuous process monitoring. Serial links to variable frequency drives (VFDs), motor control centers (MCCs), and weighing systems are common applications in these environments.

Marine & Offshore: Shipboard automation and offshore platform control systems benefit from the IC695CMM004LT's compact form factor and multi-protocol flexibility, enabling integration with navigation instruments, engine monitoring systems, and ballast control panels within space-constrained marine control cabinets.

Q1: Is the IC695CMM004LT compatible with both new RX3i backplanes and legacy Series 90-30 migration architectures? The IC695CMM004LT is designed exclusively for the PACSystems RX3i universal backplane (IC695CHS series). It is not directly compatible with Series 90-30 (IC693) backplanes. However, in migration projects where Series 90-30 systems are being upgraded to RX3i, the IC695CMM004LT can replicate and expand upon the serial communications functionality previously provided by IC693CMM302 or IC693CMM311 modules, often consolidating multiple legacy modules into a single 4-port unit. Configuration is performed through Proficy Machine Edition, which supports side-by-side project management for both platforms during phased migration.

Q2: How does the IC695CMM004LT support long-term maintenance and diagnostic efficiency in a running production system? The module provides port-level status LEDs for immediate visual fault identification and integrates with the RX3i CPU's fault table and diagnostic data blocks, enabling PLC-based fault annunciation and SCADA alarm generation without additional hardware. Firmware updates can be managed through Proficy Machine Edition without removing the module from service in most configurations. NANKMOS supplies the IC695CMM004LT with a 12-Month Warranty and pre-shipment functional testing documentation, supporting your maintenance team's spare parts qualification and incoming inspection processes.

Q3: What is NANKMOS's inventory availability and lead time for the IC695CMM004LT, and what quality assurance measures are applied before shipment?
