Discontinued MTL4000 series isolated barrier MTL4041B REPEATER POWER SUPPLY 4/20mA, smart, for 2- or 3-wire transmitters.

The MTL4041B provides a fully floating dc supply for energising a conventional 2- or 3-wire 4/20mA transmitter or a ‘smart’ transmitter located in a hazardous area, and repeats the current in another circuit to drive a safe-area load. For smart transmitters, the unit allows bi-directional transmission of digital communication signals superimposed on the 4/20mA signal so that the transmitter can be interrogated either from the operator station or by a hand-held communicator (HHC). The module can also be used with hazardousarea current sources and some vortex and turbine meters.
