Technical Specifications Board Type: VMEbus Analog Input Board Bus Standard: VME bus interface Input Signal: Analog voltage / current field signals Resolution: Follow VMIVME‑3122 series hardware specification Power Supply: Powered by VME chassis back‑plane Operating Temperature: 0 °C to +60 °C Storage Temperature: ‑40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Form Factor: Standard VME single‑height board Certifications: CE industrial automation board compliance
Functional Features Multi‑channel field analog signal acquisition. Analog‑to‑digital conversion for field sensor signals. Data transmission to main CPU via VME back‑plane bus. Hardware interrupt function for data ready notification. Signal isolation between field side and internal VME circuit.
Application Scenarios Widely used in VME‑bus industrial real‑time control system, industrial test platform, process equipment monitoring system. Collects analog sensor signals of pressure, temperature and flow rate.
Structural Characteristics Standard single‑height VME printed circuit board assembly. Gold‑plated VME back‑plane edge connector. Front‑panel mechanical fixing structure. Isolation circuit components integrated on printed circuit board.
Working Principle Field analog sensor signals enter board channels after isolation processing. Internal analog‑digital converter converts analog quantity into digital data. The digital data is transmitted to VME host CPU through back‑plane bus for further calculation and processing.
Installation Requirements Shut down VME chassis power before inserting board card. Insert VMIVME‑3122‑020000 into idle VME slot, tighten front‑panel fixing screws. Connect field sensor analog wiring to board signal terminals. Complete system‑side driver and resource configuration after power‑on.
