AI931S: Analog Input Module for Hazardous Area Zone 1
The AI931S is specified as Analog Input Module for Hazardous Area Zone 1. Where this variant differs from others in its family is the configuration listed below — confirm it against the unit being replaced.
This configuration's analog input module for hazardous area zone 1 is the attribute that drives the replacement decision. On a rack I/O module the configuration that matters is the one that decides whether the unit drops into the existing slot and speaks the existing signal. analog input module for hazardous area zone 1 sets channel count, voltage or current class and isolation behaviour — the three things that decide compatibility with the backplane, the field wiring and the rest of the I/O. Matching the configuration shown in the specification table against the rack rather than a generic datasheet avoids a module that installs but does not interface.
