Detailed Product Description

MTL4541A/AS current repeater 4/20mA passive i/p for HART® transmitters

MTL4541A provides an input for separately powered 4/20mA transmitters and also allows bi–directional transmission of HART communication signals superimposed on the 4/20mA loop current. Alternatively, MTL4541AS acts as a current sink for a safe-area connection rather than driving a current into the load.
