Your Jaquet T401, T402 or T412 is discontinued, and the machine still needs a speed switch. Istec SpeedSys T10 is the functional replacement: one sensor input, two high-speed relays, 4–20 mA, frequency output and Modbus TCP in a single unit. OEM NORDIC supplies it.
Watch the T10 work, step by step
One speed sensor signal goes in; relay action and outputs come out. Walk through it in 3D, with illustrative values. Press play or jump to a chapter.
- Everything on one channel. Two relays, 4–20 mA, frequency output, digital input, Modbus TCP.
- Measured and switched quickly. 0.3 Hz–35 kHz, 0.05 % accuracy, relay hardware 4 ms or less.
- Small footprint. DIN-rail housing 22.5 mm wide.
- Drop-in route off Jaquet. T401, T402, T412.

Questions we hear most
Which Jaquet tachometers does T10 take over from?
T401, T402 and T412 – Istec developed T10 for exactly these. The T411 has its own successor, T11, with a built-in display. Send us the Jaquet type and we confirm the match before you order.
Do I have to change my speed sensors?
Usually not. T10 accepts three-wire Hall, PNP, NPN and eddy-current sensors and two-wire electromagnetic sensors, and it flags a broken sensor circuit.
How quickly does it react?
Relay hardware responds in 4 ms or less. Typical total reaction is 14 ms or less at the default measuring time, and 6 ms or less at 2 ms.
Can T10 act as overspeed protection?
T10 is a speed monitor and switch. For certified overspeed protection, ask about SpeedSys 200.
