MTT MS3737 Slim Plug-In Distributor (Non-Isolation between Input and Output)

The MTT MS3737 is a slim plug-in distributor that powers a 2-wire loop transmitter and splits its 4-20mA signal into two usable outputs, a voltage output and a current output, without isolating the input and output circuits from each other. Keeping input and output on a common path lets the unit stay compact and cost-effective, which suits installations where a full three-way isolated distributor is more than the application really needs.

Input, output, and power stay isolated from each other at the power and ground level, so it still keeps the loop clean from supply-side noise even without full channel-to-channel isolation. Like the rest of the plug-in transmitter series, the MS3737 clips into its own socket base for fast swap-out during calibration or maintenance without disturbing the field wiring, and it is available in AC, 24V DC, or high-voltage DC powered versions to fit an existing panel.
