The MTT MS3716 is a slim plug-in first-order delay signal conditioner that smooths a noisy or fluctuating DC signal before it reaches downstream equipment. Rather than passing every rapid spike or dip straight through, it applies a time-based delay so the output eases into changes gradually, filtering out jitter and giving controllers, recorders, and displays a steadier reading to work with.
The delay time constant is adjustable to suit the application, from fast damping for signals that only need light smoothing to a longer delay for heavily noisy inputs. Like the rest of the plug-in transmitter series, the MS3716 clips into its own socket base for fast swap-out during calibration or maintenance, and a second isolated output is available for feeding an independent monitoring system. 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 MS3716 used for?
It’s a signal conditioner that smooths out a noisy or rapidly fluctuating DC signal before it reaches your controller, recorder, or display, using a first-order (RC-style) delay so the output eases into changes rather than jumping with every spike.
What time constant does the MS3716 use?
The delay time constant is adjustable from 0.2 to 20 seconds and is set to your specification at order. A shorter time constant gives light smoothing; a longer one gives heavier damping for very noisy signals.
Will the MS3716 slow down my process response too much?
That depends on the time constant you choose. Tell us how noisy your signal is and how fast your process needs to respond, and we can help recommend a time constant that filters the noise without introducing more lag than your control loop can tolerate.
Can the MS3716 provide two separate outputs?
Yes — a second isolated output is available, so the smoothed signal can feed a controller and a separate monitoring or logging system at the same time.
How do I know if I need the MS3716?
If your process signal is noisy or jittery and it’s causing your controller or display to hunt or flicker, a first-order delay conditioner like the MS3716 can clean it up. Send us your signal type and how noisy it is and we can confirm the right time constant.
