XYCOM XVME-428/2
XYCOM XVME-428/2 Overview
The XYCOM XVME-428/2 is an Intelligent Asynchronous Serial Communication Module (IASCM) within the XYCOM VMEbus series. It is widely used in industrial automation, process control, and embedded control systems as a communication interface between the mainframe controller and upper-level devices such as CPUs or PLCs, enabling high-speed and reliable serial data exchange.
1. Basic Features
| Item | Description |
|---|---|
| Module Type | VMEbus IASCM (Intelligent Asynchronous Serial Communication Module) |
| Supported Bus | VME64x (compatible with VME64 and VME32) |
| Communication Interfaces | Multiple RS-232 / RS-422 / RS-485 asynchronous serial ports (supporting various baud rates) |
| Power Supply | 24 V DC (VME standard compliant power input) |
| Operating Temperature | –20 °C to +70 °C with industrial-grade thermal design |
| Reliability | High reliability and strong EMI resistance, suitable for harsh industrial environments |
| Form Factor | Standard 6U VME card dimensions |
2. Functional Highlights
- Multi-channel Serial Communication:
Supports simultaneous connection of multiple asynchronous serial devices (sensors, actuators, instruments, etc.) for centralized management. - High-speed Data Transfer:
Leverages the high-bandwidth VME64x bus to ensure real-time performance. - Intelligent Processing:
Built-in protocol handling and buffer management reduce the workload of the host system. - Modular Integration:
Can be combined with other XYCOM XVME series modules—such as digital I/O, counter, or analog cards—to form a complete control system.
3. Typical Applications
- Industrial Automation: Serial data acquisition and control between PLCs and field devices.
- Process Control (DCS): Centralized collection and reporting of multi-point instrument data.
- Embedded Control: Serial communication bridging on VME-based embedded platforms.
- Test and Measurement: Interface solution for laboratory or production-line instruments.
