AAR181-S50: 12 Channel Isolated RTD Input Module
The AAR181-S50 is the 12 Channel Isolated RTD Input Module covered on this page. The attribute that decides whether it fits the existing installation without modification is 0.2 kg.
The reason to specify this exact variant is 12 channel isolated rtd 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. 12 channel isolated rtd 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 0.2 kg against the rack rather than a generic datasheet avoids a module that installs but does not interface.
