PAGE 6 Current Input Module, -20 mA to +20 mA, Two or Four Channels Specifications 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 page 9. Check the table on page 3 for 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.
