Description
The SNAP-AOA-23-iSRC and SNAP-AOA-23-iSRC-FM
modules provide a nominal output range of 4 mA to 20 mA.
These modules include built-in loop sourcing capability.
The SNAP-AOA-23-iSRC-FM is Factory Mutual approved.
With the connection of a single 24 V power supply, these
modules source two 24 V loops. The loop sources are
internally connected to the individual outputs.
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.
SNAP Analog Output Modules
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.
