Description
The SNAP-AIMA-iSRC and SNAP-AIMA-iSRC-FM are similar to
the SNAP-AIMA-i module but include built-in loop sourcing
capability. With the connection of a single 24 V power
supply, these modules source 24 V for two 4–20 mA loops.
The loops are internally connected to the individual inputs.
The two channels and their loop sources are isolated from
each other; they do not share any field connection. In
addition, each loop source is current limited so that an
external fault on one loop will not affect the other.
The SNAP-AIMA-iSRC-FM is Factory Mutual approved.

IMPORTANT: The mounting rack connector has 24 pins; the
module connector has 20 pins. The extra pins on the
mounting rack connector prevent misalignment of the
module during installation.
