Item
Description
Product Type
VME-bus 6U dual-slot digital I/O module
Part Number
70240-001 (REV 1.1)
Channel Count
80 TTL digital I/O channels (8 × 8-bit ports)
Per-Port Function
Each 8-bit port includes 8 I/O lines + 1 flag output
Electrical Specs
TTL level 0 V ~ 5 V; each output can source ≈ 20 mA (typical TTL drive)
Board Form Factor
6U (dual-slot) VME-bus standard
Main Features
• Programmable as input or output
• Supports interrupt / flag output
• C-language firmware based on RTOS for easy portability
Applications
Industrial control, data acquisition, real-time monitoring, and embedded systems requiring large-scale discrete I/O within VME environments
The XYCOM XVME-240 is a high-density digital I/O card designed for VME-bus systems. It provides 80 TTL-compatible I/O channels organized into eight 8-bit ports, each featuring an additional flag output for use in interrupt or status signaling.
The module adopts a 6U dual-slot form factor compliant with the VME-bus standard, ensuring compatibility for direct plug-in installation within existing VME systems. Power and signal interfaces follow standard VME specifications.
Its firmware is implemented on a real-time operating system (RTOS), offering high code portability and reliable real-time responsiveness, making it ideal for industrial automation, measurement, and control applications that demand fast and deterministic I/O performance.

DCS vs. PLC vs. SCADA: What’s the Difference?
While DCS, PLC (Programmable Logic Controller), and SCADA (Supervisory Control and Data Acquisition) systems are all used in industrial automation, they serve different purposes:
-
A DCS is ideal for complex processes requiring high reliability and coordinated control over a large area.
-
A PLC is typically used for discrete control tasks such as assembly lines or machinery.
-
SCADA focuses on supervisory-level monitoring and data gathering across geographically dispersed assets.
In many modern installations, DCS and SCADA functionalities are integrated to leverage the strengths of both systems.
Applications of Distributed Control Systems
DCS technology is widely applied in industries such as:
-
Oil & Gas Refining
-
Power Generation
-
Chemical and Pharmaceutical Manufacturing
-
Water and Wastewater Treatment
-
Food and Beverage Processing
Conclusion
A Distributed Control System (DCS) offers a robust, scalable, and efficient solution for managing complex industrial processes. Its distributed nature not only enhances reliability and safety but also supports continuous operational improvement through integrated monitoring and control. Industries relying on precision, safety, and uptime continue to adopt and evolve DCS technology for smarter automation.
