Product Details

IC695CPE305-ABAH Product Description

The GE IC695CPE305-ABAH is a high-performance CPU module engineered for the PACSystems RX3i control platform, delivering deterministic scan performance, integrated dual-port Ethernet, and seamless compatibility across the full RX3i backplane ecosystem. Designed for demanding industrial environments where system consistency, modular scalability, and long-term maintainability are non-negotiable, the IC695CPE305-ABAH serves as the computational core of a layered automation architecture — coordinating I/O acquisition, motion sequencing, process logic, and network communication within a unified control framework.

As a drop-in replacement and system-matched upgrade for legacy RX3i deployments, this CPU module supports direct rack integration with the IC695CHS016 and IC695CHS012 universal backplanes, enabling engineers to expand I/O capacity without redesigning the control cabinet. Its dual embedded Ethernet ports support SRTP, Modbus TCP, and EGD (Ethernet Global Data) protocols natively, allowing the IC695CPE305-ABAH to participate in peer-to-peer data exchange, SCADA integration, and distributed I/O architectures without requiring a dedicated communications coprocessor.

Every IC695CPE305-ABAH unit supplied by NANKMOS undergoes pre-shipment functional verification, covering power-on diagnostics, memory integrity checks, and communication port validation. A 12-Month Warranty is included as standard, supporting procurement teams managing long-cycle maintenance contracts and capital equipment budgets across manufacturing, energy, and process industries.

The IC695CPE305-ABAH achieves its full architectural value when deployed within a complete PACSystems RX3i platform. At the power layer, the IC695PSA040 or IC695PSD040 power supply modules provide stable, regulated DC power to the backplane, ensuring the CPU and all installed I/O modules operate within specified voltage tolerances — a critical factor for deterministic scan cycle performance in high-speed process applications.

At the I/O layer, the IC695ALG600 analog input module and IC695MDL765 discrete output module extend the CPU's reach into field instrumentation, enabling direct acquisition of 4–20 mA process signals and digital actuator control within the same rack. For applications requiring high-density discrete I/O, the IC694MDL660 and IC694MDL940 modules integrate seamlessly via the universal backplane, preserving the mixed-series compatibility that defines the RX3i platform.

Communication architecture is extended through the IC695ETM001 Ethernet interface module, which offloads network traffic management from the CPU's embedded ports — essential in architectures where simultaneous SCADA polling, peer-to-peer EGD exchange, and HMI data serving would otherwise compete for bandwidth. For PROFINET-based field device integration, the IC695PNC001 PROFINET Controller module enables deterministic real-time I/O communication with distributed field devices, drives, and safety modules without burdening the CPU scan cycle.

At the HMI layer, GE's QuickPanel+ operator terminals connect directly to the IC695CPE305-ABAH via Ethernet, providing operators with real-time process visualization, alarm management, and trend logging. For motion-intensive applications, the IC695ALG616 high-speed analog output module supports coordinated multi-axis positioning when paired with compatible servo drives, extending the CPU's control authority into precision motion sequences.

Redundancy-critical installations benefit from pairing the IC695CPE305-ABAH with the IC695RMX128 redundancy memory exchange module, enabling hot-standby CPU configurations where switchover occurs within one scan cycle — a requirement in power generation, water treatment, and continuous process industries where unplanned downtime carries significant operational cost.

Manufacturing & Discrete Assembly: In automotive body-in-white lines and electronics assembly systems, the IC695CPE305-ABAH manages multi-zone conveyor sequencing, robot handshake interlocking, and vision system integration. Its deterministic Ethernet communication ensures that upstream MES systems receive accurate production counts and fault codes without scan cycle jitter.

Power Generation & Utilities: Turbine auxiliary control panels and substation automation systems rely on the RX3i platform's proven reliability. The IC695CPE305-ABAH coordinates generator protection relay inputs, breaker status monitoring, and load-shedding logic within a single rack, reducing panel footprint and simplifying IEC 61850 integration via the ETM001 communications module.

Oil, Gas & Petrochemical: In wellhead control panels and compressor station automation, the CPU's wide operating temperature range and robust memory architecture support continuous 24/7 operation in environments subject to vibration, humidity, and temperature cycling. Integration with IC695ALG600 analog modules enables direct 4–20 mA pressure and flow signal acquisition without external signal conditioning.

Water & Wastewater Treatment: Municipal SCADA systems managing pump stations, filtration control, and chemical dosing benefit from the IC695CPE305-ABAH's dual Ethernet ports, which allow simultaneous connection to a plant-wide SCADA network and a local HMI without requiring a network switch at each remote station.

Mining & Metals: Conveyor drive coordination, crusher sequencing, and ore processing control systems demand CPUs capable of managing large I/O point counts with fast scan cycles. The IC695CPE305-ABAH's 64 MB user memory accommodates complex ladder logic programs with extensive data logging, fault history, and production reporting functions.

Q1: Is the IC695CPE305-ABAH backward compatible with IC694 series I/O modules installed in an existing RX3i rack?Yes. The PACSystems RX3i universal backplane (IC695CHS016 / IC695CHS012) supports mixed installation of IC695 and IC694 series modules in the same rack. The IC695CPE305-ABAH communicates with IC694 analog and discrete I/O modules natively through the backplane bus, preserving existing I/O wiring and eliminating the need for rack replacement during CPU upgrades. This backward compatibility is a core design principle of the RX3i platform and is validated through GE's published hardware compatibility matrices.

Q2: What redundancy architecture is supported, and what is the typical switchover time?The IC695CPE305-ABAH supports hot-standby CPU redundancy when paired with the IC695RMX128 Redundancy Memory Exchange module and a second IC695CPE305-ABAH unit in a mirrored rack configuration. Memory synchronization occurs continuously over the RMX link, and switchover from primary to standby CPU is completed within one scan cycle (typically <10 ms for standard program sizes). This architecture is suitable for applications governed by IEC 61511 SIL 1–2 requirements and is commonly deployed in power generation, water treatment, and continuous chemical process control.

Q3: What does the 12-Month Warranty cover, and how does NANKMOS support long-term spare parts availability?Every IC695CPE305-ABAH supplied by NANKMOS is covered by a 12-Month Warranty against manufacturing defects and functional failure under normal operating conditions. Pre-shipment testing includes power-on diagnostics, memory verification, and Ethernet port functional checks. NANKMOS maintains dedicated inventory of PACSystems RX3i CPU modules, power supplies, and I/O modules to support maintenance contracts, emergency replacements, and planned shutdown spares procurement.
