Technical Specifications Applicable Platform: PACSystems RX7i PLC rack Module Type: System auxiliary accessory module Backplane Interface: RX7i high‑speed VME backplane bus Operating Power: Powered by RX7i rack backplane Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot VME form‑factor module for RX7i rack Certifications: CE, UL industrial component compliance
Functional Features Realizes auxiliary supporting functions for PACSystems RX7i control system. Exchanges status and configuration data with RX7i CPU via VME backplane bus. Front‑panel LED indicators reflect module running and fault status. Supports hot‑swap replacement under system running condition. Built‑in self‑diagnosis circuit for hardware abnormality detection and reporting.
Application Scenarios Auxiliary hardware configuration for PACSystem
s RX7i automation control cabinet. Special function expansion for chemical, power industry RX7i process‑control projects. Spare‑part replacement for existing RX7i industrial control installations.
Structural Characteristics Standard single‑slot VME plug‑in structure matching RX7i rack specification. Front‑panel LED status indicator lamps for module working condition. Backplane golden‑finger VME bus interface for data communication and power acquisition. Locking fasteners for stable fixing inside rack against vibration displacement.
Working Principle The module acquires operating power from RX7i VME backplane bus. It receives configuration parameters from RX7i CPU, executes corresponding auxiliary functions, and uploads module status and diagnostic information to main controller through backplane bus. On‑board monitoring circuit keeps detecting internal hardware running state all the time.
Installation Requirements Insert module into designated VME slot of PACSystems RX7i standard rack. Rack protective grounding must strictly comply with official system grounding specification. Hot‑swap replacement operation shall follow on‑site industrial safety operation procedure. Ambient operating environment shall keep within defined temperature and humidity range without condensed moisture.
