– Key Features
Galvanic isolation on all I/O channels provides ground-loop immunity and protection against transient overvoltages. Byte-boundary configuration enables flexible input/output mode assignment within the 32-channel architecture. Programmable debounce filtering on digital inputs suits varying mechanical switch and sensor response characteristics. Front-panel diagnostics and built-in test capability streamline field verification and troubleshooting.
– Typical Applications
Digital sensor interfacing, relay and solenoid control, machinery interlocking, status monitoring, and distributed process automation requiring isolated multi-channel I/O in VMEbus-based systems.
– Compatibility & Integration
Software compatible with VMIVME-2532 and VMIVME-2533 relay output boards. Standard VMEbus connectors enable integration into existing crate systems and IIOCs.
