Technical Specifications Backplane Power Consumption:290mA @5VDC Redundancy Link Rate:High‑speed dedicated redundancy bus Isolation Voltage:1500V RMS Operating Temperature:0℃～+60℃ Storage Temperature:-40℃～+85℃ Relative Humidity:5%‑95%, non‑condensing Certifications:CE, UL, cUL
Functional Features EN version redundancy firmware, primary‑standby CPU status monitoring, synchronization management, bumpless switch‑over control, redundancy fault diagnosis, front‑panel status LED indication.
Application Scenarios Redundant RX3i system spare replacement, high‑availability control cabinet requiring EN firmware revision.
Performance Parameters Fast redundancy fault detection Stable switch‑over logic execution Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel LED indicators for redundancy running and fault status Dedicated redundancy link connection interfaces Backplane gold‑finger bus contact Internal redundancy logic circuit loaded with EN firmware Mechanical locking latch
Working Principle Consistent with IC695CRU320. EN firmware defines redundancy monitoring and switch‑over logic rules. Module monitors running status of primary and standby CPU through redundancy link, executes switch‑over sequence upon primary unit failure, records redundancy fault information.
Installation Requirements Install into designated redundancy slot of RX3i redundant rack. Reliable cabinet protective grounding. Connect official redundancy cables as per manual. Power‑off rack for module replacement. Ensure cabinet heat‑dissipation ventilation.
Usage Notes Confirm EN firmware compatibility with matched CPU. Regularly inspect redundancy link connection. Judge redundancy operating status by LED indicators. On‑site disassembly is prohibited. Avoid corrosive gas and liquid splash.
