Description
The SNAP-AIMA-8 module provides an input range of -20mA
to +20mA with eight channels of analog current input. (If you
need a similar module with 32 channels, see
SNAP-AIMA-8 can be used with SNAP PAC brains and rack-
mounted controllers only. These modules DO NOT supply
loop excitation current.
Since all inputs share a common reference, the module must
be installed at the beginning or end of a typical 4–20mA loop.
If you are using both standard and self-sourcing transmitters,
either put the transmitters on different modules or use
different power supplies. If you need channels that are
isolated from each other on the same module, see Opto 22
form #1182.
If you have multiple self-sourcing transmitters that share the
same positive common, do not use this module. Use the
SNAP-AIMA-i module instead. See Opto 22 form #1182.
4-20 self-powered (self-
sourcing) transmitters
SNAP-AIMA-8
See additional wiring diagrams on
NOTE: For transmitters sharing the plus side of the loop power
supply, the input current will be read as a positive current.
