MTL 4500 Intrinsically Safe Isolators  MTL4541A/AS

MTL4541A/AS – MTL5541A/AS CURRENT REPEATER 4/20mA passive i/p for HART® transmitters The MTLx541A 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 MTLx541AS acts as a current sink for a safe-area connection rather than driving a current into the load.
