Environmental Specifications

‑ Operating temperature：0 ℃ ~ +60 ℃ ‑ Storage temperature：‑40 ℃ ~ +85 ℃ ‑ Relative humidity：5%‑95% non‑condensing ‑ Installation location：Indoor cabinet, IP20 ‑ EMC compliance：IEC 61000‑6‑2 ‑ Certifications：CE, UL Class I Div 2 hazardous‑location certification

Mechanical Data

‑ Weight：approx 0.34 kg ‑ Dimension：RX3i single‑slot CPU module form‑factor ‑ Handling note：ESD‑sensitive high‑speed processor circuit; RTC battery needs periodic replacement; USB port only for storage‑device, not for PC direct programming

Main Functions

1. Main control core of RX3i system, execute user logic program, process analog calculation, floating‑point arithmetic, complete logic control for local and expansion‑rack I/O modules via dual PCI/serial backplane bus.
2. Multiple built‑in communication ports: Ethernet for programming, SCADA, Modbus‑TCP; RS‑232/RS‑485 for Modbus‑RTU instrument & multi‑PLC communication.
3. USB‑Host supports program backup, restore and field firmware upgrade without programming computer.
4. Without battery for program/data retention; RTC clock relies on internal battery; energy pack option realizes power‑loss automatic save to non‑volatile storage.
5. LED status indication on front panel:   ‑ Green CPU OK：CPU hardware & run status normal   ‑ Red FAULT：CPU hardware / memory / configuration fault   ‑ Green RUN：Program running state   ‑ I/O FORCE：I/O force‑on active indicator   ‑ Ethernet / COM1 / COM2：Communication activity LED

Installation & Wiring Requirements

1. Cut off rack power before replacement. Hot‑swap is forbidden for CPU module. Strict anti‑static protection when handling CPU module.
2. Insert IC695CPE310 fully into RX3i universal backplane slot and lock latch; install optional IC695ACC400 energy pack if required.
3. Network & serial wiring strictly follow GE RX3i hardware manual; use shielded twisted‑pair for RS485 bus; install terminating resistor at bus end; reliable protective‑ground connection.
4. After replacement：power‑on rack; verify CPU OK / RUN / FAULT LED status; download hardware configuration and user program; complete I/O mapping, communication link test.
5. Replacement note: Check RTC battery aging status; confirm total backplane power‑supply load capacity; full‑system commissioning test mandatory before unit put‑into‑service。
