Description
The SNAP-AIMA-iSRC adn 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.
