Product Features

• High Reliability: 300 V optocoupler isolation and debounce circuit ensure signal integrity, ideal for noisy environments.
• Modular Hot Swapping: Allows replacement during system operation, reducing maintenance downtime.
• Wide Voltage Compatibility: 5‑50 V DC input range adapts to various power supply configurations.
• Low Power Consumption: Internal 12 V isolated power supply features low power consumption and minimal heat dissipation requirements.
• Multi-interface Compatibility: Compatible with standard VME‑bus 6U dual-slot chassis, enabling direct use in existing VME systems.

Structure and Composition

• Front-end Optocoupler Isolation Unit: Each output is equipped with an independent optocoupler for electrical isolation.
• Output Driver Circuit: Adopts Open-Collector structure, capable of directly driving loads such as relays, contactors, and LEDs.
• Power Management Module: Internal 12 V isolated power supply provides stable power and includes overvoltage and overcurrent protection.
• Chassis and Backplane: 6U dual-slot metal chassis, paired with VME‑bus backplane for high-speed data bus connection.

Typical Application Fields

• Industrial Automation: Digital output for CNC machine tools, PLC expansion, and robot control systems.
• Military and Aerospace: High-reliability digital signal driving for flight control, weapon systems, and satellite ground stations.
• Process Control: Switch control of on-site equipment such as solenoid valves, relays, and indicator lights.
• Test and Measurement: Digital output interface for laboratory instruments and automated test platforms.

Installation and Maintenance Notes

• Installation Method: Mount via DIN rail or directly insert into the 6U dual-slot of the VME‑bus backplane, ensuring secure latching.
• Hot Swapping: The module can be plugged/unplugged during system operation, but it is recommended to cut off power or place the bus in an idle state first to prevent transient shocks.
• Wiring Notes: The output terminal is Open-Collector; an external pull-up resistor or load-side power supply is required during use. Do not connect the load directly to the module output without a pull-up resistor.
• Protection Measures: For use in harsh environments, ensure the chassis seal meets IP65 standards to prevent dust and water intrusion.
• Fault Diagnosis: The module has a built-in self-test function, allowing quick location of output channel faults or overcurrent conditions by reading status registers via VME‑bus.
• Maintenance Cycle: It is recommended to perform a functional inspection every 12 months, focusing on optocoupler isolation voltage, output current, and chassis sealing.
