Product Details

IC695CHS016LT Product Description

The GE IC695CHS016LT is not simply a passive enclosure — it is the structural and electrical backbone of the entire PACSystems RX3i control platform. In a fully realized automation architecture, the chassis defines the physical and logical boundaries of the control node, determining how many modules can participate in the control loop, how signals are routed across the backplane, and how the system scales as process demands evolve.

At the control layer, the IC695CHS016LT hosts the primary CPU module — typically the IC695CPE305, IC695CPE310, or IC695CPE400 — which executes the ladder logic, function block diagrams, or structured text programs that govern the entire process. The 16-slot configuration provides ample room to co-locate the CPU alongside a full complement of I/O and communication modules without requiring expansion chassis in most mid-scale applications, reducing inter-chassis latency and simplifying cabinet layout.

At the I/O layer, the chassis accommodates discrete input modules such as the IC694MDL655 and IC694MDL754, as well as analog input and output modules like the IC695ALG600 and IC695ALG704. These modules connect directly to field instruments — pressure transmitters, flow meters, thermocouples, and actuators — and their signals are routed through the backplane to the CPU without the signal degradation that can occur in distributed I/O topologies. The IC695CHS016LT's high-speed serial backplane ensures that scan cycle times remain consistent even when all 16 slots are populated with high-density I/O modules.

At the communication layer, the chassis supports the installation of dedicated communication modules such as the IC695ETM001 for EtherNet/IP and PROFINET connectivity, and the IC695PBM300 for PROFIBUS DP master functionality. These modules allow the RX3i controller to serve as the network master for distributed I/O islands, variable frequency drives, intelligent motor control centers, and remote HMI panels. The IC695CMM002 serial communication module further extends connectivity to legacy Modbus RTU devices and third-party instrumentation, ensuring that the RX3i platform can integrate into brownfield environments without requiring wholesale replacement of existing field devices.

At the power layer, the IC695CHS016LT is designed to accept GE RX3i power supply modules — including the IC695PSA040 (120/240 VAC input) and IC695PSD040 (24 VDC input) — which mount directly into the chassis and distribute regulated DC power across the backplane to all hosted modules. This integrated power architecture eliminates the need for external DIN rail power supplies for module logic power, reducing wiring complexity and improving power distribution reliability within the control cabinet.

At the HMI layer, the RX3i controller hosted in the IC695CHS016LT communicates with operator interface terminals — such as GE's QuickPanel+ series or third-party SCADA systems — via the EtherNet/IP or OPC-UA protocols supported by the IC695ETM001 communication module. This allows operators to monitor real-time process variables, acknowledge alarms, and adjust setpoints from a centralized HMI without interrupting the control program execution on the CPU.

For redundancy-critical applications, the IC695CHS016LT can be deployed as part of a Hot Standby CPU redundancy architecture using the IC695CHS016 paired with a redundant CPU module and the IC695RMX128 redundancy memory exchange module. In this configuration, two RX3i chassis operate in lockstep, with the standby CPU continuously synchronized to the primary. In the event of a primary CPU fault, the standby assumes control within one scan cycle, ensuring uninterrupted process operation in power generation, water treatment, and petrochemical applications where downtime carries significant operational or safety consequences.

At the protection layer, the chassis architecture supports the integration of safety I/O modules compliant with IEC 61508 SIL 2 requirements, enabling the RX3i platform to serve as the foundation for Safety Instrumented Systems (SIS) in process industries. When combined with the IC695ETM001 and appropriate safety-rated field devices, the IC695CHS016LT-based control node can manage emergency shutdown sequences, fire and gas detection responses, and high-integrity pressure protection systems within a unified control architecture.

At the maintenance layer, the 16-slot chassis design supports hot-swap module replacement for select I/O modules, allowing maintenance technicians to replace faulty modules without powering down the entire chassis. Combined with the RX3i CPU's built-in diagnostics — accessible via the Machine Edition programming software — engineers can identify module faults, communication errors, and I/O channel failures remotely, reducing mean time to repair and minimizing unplanned downtime across the asset lifecycle.

Manufacturing & Discrete Automation: In automotive assembly lines and electronics manufacturing facilities, the IC695CHS016LT serves as the central control chassis for robotic cell controllers, conveyor sequencing systems, and vision-guided assembly stations. Its 16-slot capacity allows a single chassis to host the CPU, motion coordination modules, and high-density discrete I/O required to manage multi-axis pick-and-place operations and quality inspection gates within a compact panel footprint.

Power Generation & Utilities: In gas turbine control systems and combined-cycle power plants, the IC695CHS016LT provides the backplane infrastructure for turbine sequencing controllers, excitation system interfaces, and generator protection relay communication modules. The chassis's support for redundant CPU configurations ensures that control continuity is maintained during scheduled maintenance windows and unplanned component failures, meeting the high-availability requirements of grid-connected generation assets.

Petrochemical & Refining: In distillation column control and compressor surge protection applications, the IC695CHS016LT hosts the analog I/O modules and communication gateways required to interface with field-mounted pressure, temperature, and flow transmitters. The chassis's robust backplane architecture supports the high-speed analog scan rates required for tight PID loop control in processes where temperature or pressure excursions can result in product quality degradation or equipment damage.

Water & Wastewater Treatment: Municipal water treatment facilities deploy the IC695CHS016LT as the primary control chassis for pump station automation, chemical dosing systems, and filtration process control. The chassis's EtherNet/IP communication capability allows it to integrate with SCADA systems for remote monitoring of distributed pump stations across a water distribution network, reducing the need for on-site operator presence at remote locations.

Mining & Metals Processing: In ore processing plants and smelting operations, the IC695CHS016LT provides the control infrastructure for conveyor drive coordination, crusher sequencing, and flotation cell level control. The chassis's wide operating temperature range and compatibility with conformal-coated I/O modules make it suitable for deployment in the dusty, high-vibration environments characteristic of mineral processing facilities.

Q1: Is the IC695CHS016LT compatible with legacy Series 90-30 I/O modules? The IC695CHS016LT is a PACSystems RX3i universal backplane chassis and is not directly compatible with legacy GE Series 90-30 (IC693 series) I/O modules. However, the RX3i platform supports the IC695LRE001 local rack expander, which allows Series 90-30 expansion racks to be connected to the RX3i main chassis via a high-speed serial link, enabling gradual migration from legacy 90-30 architectures to the RX3i platform without requiring immediate replacement of all existing I/O modules. For full Contextual Integration with modern PROFINET and EtherNet/IP networks, we recommend transitioning to native RX3i I/O modules over the course of a planned upgrade cycle.

Q2: Can the IC695CHS016LT support a Hot Standby redundancy configuration, and what additional components are required? Yes. The IC695CHS016LT supports GE PACSystems RX3i Hot Standby CPU Redundancy when paired with a compatible redundant CPU module (such as the IC695CPE330 with redundancy firmware) and the IC695RMX128 Redundancy Memory Exchange module. Two IC695CHS016LT chassis are required — one for the primary controller and one for the standby — connected via a dedicated fiber-optic redundancy link. The redundancy architecture provides bumpless transfer with sub-scan-cycle switchover times, making it suitable for continuous process applications in power generation, petrochemical, and water treatment facilities where unplanned downtime is not operationally acceptable.
