The MTT MS3707H is a slim plug-in distributor built for 2-wire HART transmitters, powering the transmitter loop and reproducing its 4-20mA signal as a galvanically isolated output while passing the HART digital communication signal through undistorted. That means a HART configuration tool can still talk to the field transmitter through the isolator, while the receiving control system sees a clean, isolated 4-20mA signal.
Front-accessible zero and span trimmers make on-site calibration quick, and like the rest of the plug-in transmitter range, the MS3707H clips into its own socket base so the unit can be swapped for calibration or replacement in seconds without disturbing the field wiring. Flexible AC or DC power plus wall or DIN rail mounting make it easy to fit into an existing panel, making it a straightforward way to add loop isolation to a HART-enabled instrument without losing HART communication.
