MTL4641A/AS CURRENT REPEATER 4/20mA passive i/p for HART® transmitters.
The MTL4641A 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, the MTL4641AS acts as a current sink rather than driving a current into the load.
