2MLI-A21A: MasterLogic 200 I/O Module
The 2MLI-A21A is specified as MasterLogic 200 I/O Module. Where this variant differs from others in its family is the configuration listed below — confirm it against the unit being replaced.
The reason to specify this exact variant is masterlogic 200 i/o 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. masterlogic 200 i/o 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 the configuration shown in the specification table against the rack rather than a generic datasheet avoids a module that installs but does not interface.
