GI/IS Analog Input IOTA Model CC-GAIX21
The model CC-GAIX21 Analog Input IOTA accommodates up to sixteen high level DC signals. This IOTA does not support redundancy and allows galvanically isolated inputs from the MTL4544 (two channel) isolator.
- MTL4544 - Dual channel 4-to-20 mA isolator with HART®
- MTL4599 - Dummy, terminates unused connectors
Refer to “GI/IS IOTA models” on page 582 for a complete list of supported Series C IOTA and their corresponding isolators.
Analog Input Supported Isolators
The following table defines important distinctions between the various isolators and the Analog Input IOTAs they support.
