Description
- Channel Configuration: 32 optically isolated DI + 32 optically isolated DO
- Input Voltage Range: 5 ~ 125 VDC
- Output Sink Current: 300 mA per channel, maximum output voltage 50 VDC
- Isolation Rating: 1000 V continuous, 3500 V 1-second impulse isolation
- Bus Interface: VMEbus A16/A24 addressing, D08/D16/D32 data transfer
- Power Consumption: +5 VDC @ 2.65 A
- Operating Temperature: 0 °C ~ +60 °C
- Storage Temperature: -55 °C ~ +85 °C
Function Features:
- Built-in self-test (BIT) function for offline and online hardware diagnosis
- Programmable input contact debounce timing
- Output disable function during maintenance testing
- Optical isolation eliminates ground loop interference
Application Scenarios:
Industrial VME embedded control systems, aerospace test equipment, power plant control systems, military automation equipment
Material Composition:
6U Eurocard PCB, optocoupler isolation components, metal front panel, two 64-pin DIN field connectors
Structural Features:
Single-slot 6U VME form factor, pluggable into standard VME chassis backplane; front panel equipped with field wiring connectors
Working Principle:
Optocoupler separates field-side digital signals and VME controller bus; input circuits detect external contact or voltage status; output circuits drive external loads via open-collector circuits under bus command
Installation Requirements:
Install inside ventilated VME chassis; use shielded cables for long-distance field wiring
Usage Notes:
Observe maximum single-channel output current limit; configure debounce parameters for mechanical contact inputs; avoid continuous operation at upper temperature limit
