MTT MS3108 Terminal Block Type Frequency/Analog Converter

We get this enquiry from customers with a flow meter, tachometer, or similar sensor giving a pulse output, who need that one reading to feed two different systems — say a PLC for control and a separate totalizer or recorder for record-keeping. Wiring the pulse output to two devices at once often means one input loads down the other, and there’s no isolation between the two.

The MTT MS3108 handles this properly. It reads a pulse train — dry contact, open collector, AC or DC voltage pulse, or even a pulsed 4-20mA signal — and converts it into two independent, isolated DC outputs from a single unit. This looks simple, but in actual application, sensors and pulse types vary a lot from site to site, so the MS3108’s wide input range means it usually drops straight into an existing installation without changing the sensor wiring.

Full isolation between input, both outputs, and power keeps every connected device electrically separate and blocks noise picked up along a long pulse-cable run or from a switching sensor. A choice of AC or DC power supply lets it fit panels without a dedicated low-voltage bus, and it mounts on standard DIN rail right where the pulse wiring lands.

Before we quote, we would normally check: the sensor’s pulse type and frequency range, the output ranges needed on Output 1 and Output 2, the panel’s available power supply (AC or DC, and voltage), and DIN-rail space (it’s a compact 49.8mm wide unit). Send us these details and we can confirm the right variant before you order. Hope this helps.
