The SNAP-AOA-23-iSRC module provides two channels of current output with a nominal output range of 4 mA to 20 mA. The module includes built-in loop sourcing capability.
With the connection of a single 24 V power supply, the module sources 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.
