The AIM Analog Input Module
The Analog Input Module (AIM) isolates and
conditions four analog signals and relays input
information to the NCS Interface Module.
All Channels: 4-20mA Filter 60Hz
Input Scaling: Disabled
Trimming: Disabled
Custom Curve: Disabled
Default Configuration
Note:
Earlier Models
have a different
DIN latch but
overall dimensions
are the same and
both versions are
interchangeable.
