XYCOM XVME-240 70240-001 I/O Module
XYCOM XVME-240 70240-001
The XVME-240 is a VMEbus-based digital I/O module under XYCOM, specifically designed for industrial automation, Distributed Control Systems (DCS), and SCADA environments. It features high I/O density and resistance to harsh industrial conditions (wide temperature range, strong vibration, and electromagnetic interference), enabling reliable input/output control in various scenarios such as power systems, petrochemical industry, and manufacturing assembly lines.

Product Features
- High I/O Density: Offers 32 digital I/O points within a 6U card width, suitable for control cabinets with limited space.
- Industrial-Grade Reliability: Designed with wide temperature resistance, vibration resistance, and electromagnetic interference resistance to meet the demands of harsh on-site environments.
- Modular Expansion: Can be combined with other XYCOM XVME series (e.g., XVME-202, XVME-244) for multi-functional expansion.
- Fast Data Transmission: Relies on the high-speed parallel VMEbus to reduce I/O latency and improve system response speed.
- Compatibility with Multiple Control Platforms: Supports interface specifications of mainstream DCS/PLC systems such as ABB, Honeywell, Yokogawa, and Emerson.
- Easy Maintenance: Card-based structure allows easy insertion and removal, enabling quick fault location.
Structure and Composition
- PCB Main Board: Carries digital I/O circuits, optocoupler isolation, regulated power supply, and VME interface chips.
- I/O Terminal Block: 24 V DC input/output terminals with screw-type wiring for convenient on-site wiring.
- Backplane Connector: Standard VME slot pins that provide signals for power supply, address, and data bus.
- Protective Enclosure: Metal frame equipped with dust-proof and moisture-proof gaskets, meeting protection ratings such as IP4-IP5.
- Optional Expansion Modules: Modules like storage, communication (Ethernet, Profibus), or analog I/O expansion cards, which can be stacked via the backplane.
Typical Application Fields
| Industry | Application Scenarios |
|---|---|
| Power Systems | Relay protection and switch control in power plants and substations |
| Petrochemical Industry | Process control, digital switching of valves/pumping stations |
| Manufacturing | I/O interfaces for assembly lines and robot workstations |
| Water Treatment | Remote monitoring of pumping stations and valves |
| Building Automation | Digital control of HVAC and lighting systems |
| Transportation | Status monitoring of rail transit and airport facilities |
Installation and Maintenance Guidelines
Pre-Installation Inspection
- Confirm that the chassis power supply meets the 5 V DC specification.
- Check that the VME backplane slot is free of dust and deformation.
Card Insertion
- Align the XVME-240 with the slot 卡口 (card slot notch), and insert it with even force until the latch locks in place.
- Ensure the latches on both sides of the card are locked to prevent falling off due to vibration.
Wiring
- Connect the 24 V DC power supply and signal lines to the corresponding terminal blocks according to the wiring diagram.
- For high-current output, it is recommended to use bolts for reinforcement and install protective fuses.
System Configuration
- Add the corresponding I/O module to the upper computer (DCS/SCADA) and map the address (usually 0x0x00-0xFF).
- Conduct functional tests using the driver provided by the supplier or the standard VME driver.
Daily Maintenance
- Regularly check the tightness of the terminal blocks to prevent false triggering caused by loosening.
- Clean the dust on the card surface to keep the heat dissipation channel unobstructed.
- If I/O abnormalities occur, first check the power supply and wiring, then read the error code through the upper computer diagnostic tool.
- When replacing the card, ensure the power is turned off to avoid electrostatic damage.
