The Acromag AVME9430-i is a 32-channel isolated digital output module for VMEbus systems. It provides individual solid-state relay (SPST-NO) outputs with galvanic isolation between channels and from the VMEbus, protecting control circuits from electrical noise and transients. Each channel supports 0 to 1A DC output at 0 to 40°C, with individual source or sink configuration. The module delivers 2.0ms maximum response time and includes on-board thermal protection with status indication and optional selective channel reset on over-temperature. User readback of output states is supported.
