Jaquet T411 single channel tachometer with display

Jaquet T411.00 · 383Z-05318 · single channel speed transmitter with display · 0-35 kHz · speed signal to relay, open collector and analog output · suitable for active and passive sensors

Note: The T411 & T412 (display units) have been declared obsolete and are only available from our latest stock.; the SpeedSys T11 offers a functional replacement.
The Jaquet T411 is a Single Channel Tachometer speed switch with display which converts absolute speed into an analog signal. This unit will measure from 0-1 Hz all the way up to 35 kHz and gives a 4-20 DCmA output, which can be configured via the included Windows software package. The T411 features a single changeover relay and includes 2 limits (A/B) with programmable hysteresis. The T411's adaptive trigger provides high noise immunity, giving a fast response to over speed conditions.
