Industrial Piezotron (IEPE) couplers with external supply, 1-channel / 5127B

The Type 5127B single-channel Piezotron (IEPE) coupler is suited for low-impedance sensors with integrated electronics (Piezotron (IEPE) sensors). The gain can be set with a jumper to either 1x or 10x. The amplifier has two series-connected second-order filters, designed as plug-in elements. The type of filter (high-pass or low-pass) as well as the frequency limit are selectable. A bandpass filter is obtained by the series connection of one high-pass and one low-pass filter. The time constant of the optional RMS converter can be selected. The limit switch is set with a potentiometer. The switching threshold set point can be monitored at the “Limit” output with a digital volt meter or an oscilloscope. The output of the limit switch is electrically isolated by an optocoupler. The following output signals are present at the 8-pole round connector: two analog output signals (Out (Filter) and Out (RMS)) and a digital output signal (Limit Switch).
