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.
