MTL4041B MTL Instruments Repeater Power Supply

MTL Instruments MTL4041B Repeater Power Supply provides a fully floating dc supply for energizing 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 hazardous area current sources and some vortex and turbine meters.
