Your Jaquet tachometer is discontinued. Your machine is not. Istec SpeedSys T10, T11, T20 and T30 are the functional replacements, and OEM NORDIC supplies them for harsh-condition projects in the Nordics and ships them worldwide.
SpeedSys in 3D – from pickup to relay
Watch a speed pickup become a hard relay trip, a 4–20 mA signal and Modbus data, then see where T10, T20 and T30 fit. Illustrative scenario, not real plant data. Press play for the voice-over.
- Fast relays. Relay hardware reacts in 4 ms or less; typical total reaction is 14 ms or less.
- Accurate. 0.3 Hz to 35 kHz at 0.05 % accuracy.
- Straight into your control system. Relays, 4–20 mA, frequency output and Modbus TCP.
- Built to last. At least the next 10 years in the Active life-cycle phase, plus Istec’s plan to support the units for at least 15 years.
Pick the unit your machine needs
T10 – one channel
Two high-speed relays, a 4–20 mA output, a frequency output, a digital input and Modbus TCP in a housing 22.5 mm wide.
Buy T10 in webshop →T11 – one channel with display
Single-channel speed monitor and switch built on the T10, with an integrated display that shows live speed. Istec lists it as the functional alternative to the Jaquet T411.
Buy T11 in webshop →T20 – two channels
A second channel and redundant power. Adds acceleration, standstill, creep and reverse-rotation monitoring, plus a channel comparison. Powered by 24 VDC.
Buy T20 in webshop →T30 – three channels
Three channels and three power inputs, software voting from 1oo2 up to 3oo3, and cross-coupled inputs.

Straight answers
Who makes SpeedSys?
Istec develops and manufactures SpeedSys. OEM NORDIC supplies it for harsh-condition projects in the Nordics and ships these units worldwide.
Who is the Istec distributor?
MK-Controls Oy is the Istec distributor, and OEM NORDIC is a business name of MK-Controls Oy. More about the company and the Istec range: mkcontrols.eu.
How long will SpeedSys be supported?
Istec expects T10, T20 and T30 to stay in the Active life-cycle phase for at least the next 10 years, and plans to support them for at least 15 years, covering customer support, documentation maintenance, repairs and spare parts. Istec notes that this may change with technology, market and regulatory developments.
Can I keep my existing speed sensors?
In most cases yes. SpeedSys accepts three-wire Hall, PNP, NPN and eddy-current sensors and two-wire electromagnetic sensors, and it monitors the sensor circuit for breaks.
Do T10, T11, T20 and T30 carry a SIL rating?
We make no SIL claim for these units. If you need a certified overspeed protection system, ask us about SpeedSys 200.
Can I buy just one?
Yes. Order one T10, T11 or T20 in the webshop. For T30 or several units, request a quote.
