Description
The SNAP-AIMA and SNAP-AIMA-4 modules provide an input
range of -20mA to +20mA. The SNAP-AIMA has two channels,
and the SNAP-AIMA-4 has four. If you need a similar module
with more channels, see
I/O processor compatibility. 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.
