Technical Specifications: Input Signal Type: Digital input signal, digital output signal Input Voltage Range: 5VDC‑125VDC Input Impedance: Standard industrial input impedance Input Current: Typical operating current, maximum limited current Response Time: ≤15 ms Channel‑to‑Backplane Isolation Voltage: 500V RMS Transient Surge Suppression: 1500V Operating Power Supply: +5VDC backplane power supply Communication Protocol: VME64 backplane bus protocol Operating Temperature: 0 °C to +60 °C Storage Temperature: -50 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard 6U single‑slot VME rack module Certifications: CE, UL, industrial EMC standard compliance
Functional Features: Supports multi‑channel digital input and output signal acquisition and level conversion. Provides hardware filtering for industrial electromagnetic interference suppression. Equipped with hardware‑based channel fault detection capability. Integrated comprehensive self‑diagnosis for channel status, power supply and internal circuitry. Does not support hot‑swap under running system condition. Real‑time fault alarm and status report to host system. Galvanic isolation between field side circuitry and VME backplane. Configurable digital I/O trigger modes via supporting software.
Application Scenarios: VME‑based industrial automation control rack. Field switch signal acquisition for manufacturing plant. Auxiliary equipment status monitoring in power plant. Interlock signal processing for petrochemical site. Industrial safety interlock control loops.
Structural Characteristics: Standard 6U single‑slot plug‑in structure compatible with standard VME rack. Front panel LED indicators for power supply, channel fault and communication status. Front‑mount terminals for field signal wiring and maintenance.
Working Principle: Field digital signals access through front terminal blocks. Hardware filter circuits remove high‑frequency noise. Optocoupler isolation units achieve galvanic separation between field circuit and internal logic circuit.
Installation Requirements: Insert module into designated slot of standard 6U VME rack. Strictly implement cabinet grounding according to system specification. Field wiring shall adopt shielded twisted‑pair cables. Separate power wiring and signal wiring to avoid crosstalk.
