Name: MTT MS3704HI Slim Plug-In High-Level Signal Conditioner
Brand: MTT Instruments
SKU: MS3704HI
Availability: InStock

The MTT MS3704HI is a slim plug-in high-level signal conditioner built as a high output load model, able to drive a receiving load of up to 1kΩ where a standard signal conditioner would be limited to a much lower resistance. It accepts a DC current or voltage input and delivers a standard 4-20mA DC output, isolated from both the input and the power supply, making it a good fit for longer wiring runs or higher-impedance receiving instruments.

Like the rest of the plug-in transmitter range, the MS3704HI clips into its own socket base so the unit can be swapped for calibration or replacement in seconds without disturbing the field wiring. Front-accessible zero and span trimmers make on-site adjustment quick, and flexible AC or DC power options plus wall or DIN rail mounting let it slot into an existing panel design without extra conversion hardware.
