Product Overview

The IC695CPU315 is a RX3i-class PAC Systems central processor module engineered for industrial control and DCS applications. It provides deterministic execution of control logic, manages I/O scanning and communications, and stores user programs and system data in battery-backed and non-volatile memory. The unit is designed for rack-based PLC/PAC systems and supports field firmware updates and robust diagnostics for continuous operation.

Key Technical Characteristics

• Processor: 1.0 GHz Celeron M-class core (embedded)

• Memory: 20 MB NVRAM (user data/program), battery-backed SRAM for real-time variables; typical user memory allocation supports hundreds of program blocks (block size and count subject to configuration)

• Program capacity: up to the platform limits (supports large program sets and symbolic variables)

• I/O reservation: discrete and analog I/O configuration memory reserved per platform conventions (typical reserved areas for I/O configuration)

• Serial communications: two onboard serial ports configurable for RS-232 and RS-485; supports Serial I/O, Modbus RTU (slave), SNP and peer protocols

• Bus support: PCI v2.2 compliant backplane interface for RX3i racks and compatible expansion modules

• Power consumption: nominally 1.2 A at 5 VDC and 1.0 A at 3.3 VDC (typical operational draw)

• Environmental: operating temperature approximately 0–60°C (32–140°F); industrial-grade tolerance for factory environments

• Timing: precise internal clock with typical accuracy within 0.01% and low daily drift (on the order of seconds/day)

• Maintainability: field-upgradable firmware, support for GE-approved auxiliary battery packs (e.g., IC695ACC302) for extended data retention

• Compliance: RoHS-compliant where applicable; HS Code commonly 8537101190 for customs classification

• Physical: weight ~0.36 kg; dimensions ~8.2 × 12.2 × 6 cm; origin: USA; condition: new, in stock

Operational Use Cases

• Primary controller for mid-to-large RX3i PAC racks in manufacturing and process automation

• Real-time machine control where deterministic loop times and serial device integration are required

• Replacement or upgrade path for MARK VLE and related series in retrofit projects

• Gateway and protocol translator in distributed control systems (Modbus/serial integration)

• Access control for redundant or multi-rack systems requiring battery-backed data retention

Integration & Commissioning Notes

• Requires RX3i-compatible chassis and backplane; verify PCI addressing and slot assignment before installation

• Install GE-approved battery modules for SRAM retention and follow replacement intervals per site maintenance plans

• Configure serial port parameters and protocol assignments in the programmer/HMI before connecting field devices

• Follow recommended grounding, cable shielding and surge protection practices to protect communications and I/O

• Perform firmware updates and configuration backups during scheduled maintenance windows to avoid production impact
