AS-B551-001: Discrete Input Module
The AS-B551-001 is the Discrete Input Module covered on this page. The attribute that decides whether it fits the existing installation without modification is 115 VAC.
What separates this variant from its siblings is discrete input module. 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. discrete input module 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 115 VAC against the rack rather than a generic datasheet avoids a module that installs but does not interface.
