Electrical Characteristics
Table 5. 2-Wire Port
1. This parameter is not tested in production. It is guaranteed by design and device characterization.
2. The longitudinal current is independent of dc loop current.
3. Current-limit I
4. IEEE is a registered trademark of The Institute of Electrical and Electronics Engineers, Inc.
5. Longitudinal balance of circuit card will depend on loop series resistance matching.
