The MTT MS3724HV is a high voltage output version of the plug-in high-level signal conditioner, built for applications where the receiving equipment needs a wider voltage swing than a standard ±10V output can give. Powered from an AC or high-voltage DC supply, it delivers an output spanning -40 to 40V, letting it drive equipment or recorders calibrated for a higher voltage range without an extra amplification stage.
It accepts a DC current or voltage input and reconditions it into that expanded output range, with zero and span independently adjustable to suit the application. Like the rest of the plug-in transmitter series, the MS3724HV clips into its own socket base for fast swap-out during calibration or maintenance without disturbing the field wiring, and flexible AC or DC power plus wall or DIN rail mounting make it easy to fit into an existing panel.

Frequently Asked Questions
What is the MTT MS3724HV used for?
It’s a high-level signal conditioner with a high voltage output, delivering a -40V to 40V swing (or -20V to 20V on a 24V DC supply) instead of the standard ±10V. It’s for driving equipment or recorders calibrated for a wider voltage range without adding a separate amplifier.
What input signals does the MS3724HV accept?
It accepts a 4-20mA DC current input (or alternative current spans) or a voltage input from 200mV to 600V span, and reconditions it into the expanded output range.
What’s the difference between the MS3724HV and the standard MS3724?
The MS3724 is a high output load model built to drive a heavier current load at standard voltage levels. The MS3724HV is built for a much wider voltage swing (±40V) rather than a heavier load. Send us your receiving equipment’s required voltage range and load, and we can confirm which model fits.
Does the output range depend on the power supply?
Yes — on a 100-240V AC or DC supply the output spans -40 to 40V; on a 24V DC supply it spans -20 to 20V. Tell us your available power supply and we can confirm the output range you’ll get.
How do I know if I need the MS3724HV?
If your receiving instrument is calibrated for an input wider than the standard ±10V range, the MS3724HV is built for that. Send us the voltage range your equipment expects and we can confirm before you order.
