Single channel tachometer speed switch with display (T-411)

The Jaquet T411.00 is a single channel tachometer speed switch 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. The T411 comes as a package with both the tachometer and a digital display.
