Application Scenarios High‑temperature factory workshop control cabinet, metallurgy auxiliary control unit, site with poor cabinet heat dissipation, high‑availability redundant system under high ambient temperature.
Performance Parameters Stable deterministic scan under high‑temperature condition Bumpless hot‑standby switch‑over Dual‑network isolated transmission Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel multi‑color LED indicators for run, fault, primary‑standby status Dual RJ45 Ethernet, RS232 and redundancy link connector Backplane gold‑finger bus contact Internal high‑temperature grade processor and memory components Mechanical locking latch
Working Principle Working flow is consistent with IC695CPU320. HU high‑temperature‑rated hardware guarantees stable chip operation under elevated cabinet temperature. Primary‑standby CPU synchronizes runtime data through redundancy link, realizes seamless switch‑over when fault occurs. Dual‑Ethernet completes multi‑network communication task. Fault events are stored inside non‑volatile memory.
Installation Requirements Mount into CPU dedicated slot of RX3i main rack. Complete cabinet protective grounding. Use official redundancy link cable. Configure redundancy and network parameters by programming software. Apply shielded Ethernet cables. Power‑off rack for module replacement. Although supporting high operating temperature, still keep cabinet ventilation as good as possible.
Usage Notes Ambient temperature shall not exceed +70℃ upper limit. I/O points shall not surpass 3072 rating. Back‑up project program and redundancy configuration. Execute redundancy switch‑over test. On‑site disassembly is forbidden. Avoid liquid splash and corrosive gas.
