Acromag / Xembedded / Xycom XVME-220 Digital Output VME Module

The Acromag / Xembedded / Xycom XVME-220 is a 32-channel digital output VME module that provides opto-isolated control signals from a VMEbus system to external devices in industrial applications. Open-collector outputs with integrated transient suppression protect against high-voltage spikes while maintaining signal integrity across demanding environments.

Technical Specifications

• 32 digital output channels arranged in 4 byte-wide output registers


• Open-collector output configuration


• Maximum output voltage: 30 V


• Maximum output current: 100 mA per channel


• Opto-isolated from VMEbus


• Transient suppression circuitry integrated


• Byte and word addressable output registers with consecutive addressing


• All outputs disabled on power-up and software reset

Key Features

• Opto-isolation ensures galvanic separation between VMEbus logic and output circuits, eliminating ground loop issues and protecting system integrity.


• Transient suppression circuitry prevents damage from inductive load switching and high-voltage transients.


• Open-collector topology allows flexible voltage and current sourcing for diverse external load types.


• Default disabled-on-startup design provides safe system initialization.


• Flexible register access via byte or word operations supports varied software architectures.

Typical Applications The XVME-220 addresses industrial automation, process control, equipment switching, relay driver interfaces, and multi-device coordination within VMEbus-based control systems requiring isolated, high-voltage output capability.

Compatibility & Integration Designed for VMEbus systems using standard VME form factor and addressing conventions. Consecutive register addressing simplifies firmware development and system integration.
