Inputs and Gain
AC / DC Coupling - is set by internal jumpers. The AC coupling is matched to both legs of the differential inputs.
IEPE - a 4mA current source is provided for use with IEPE transducers, this is set by an internal jumper. Higher currents can be set up to 10mA.
4-20 mA Input - this input is a 500 Ω resistor across the differential inputs, the incoming 4-20mA signal is converted to a 2-10V voltage signal. This input can be set to differential input to give a semi-floating input, or set to single ended to tie the input to signal zero volts.
Gain - the DIN Rail filter has 2 stages of gain before the signal filter. x1,x2,x5 and x1,x10,x100.
This gives a full 1,2,5 set of gains from 1 to x1000 (+60dB)
The standard range of Kemo lowpass and highpass filter responses can be fitted to the DIN Rail filters. A sharp notch filter, response NQ10, is available for 50Hz or 60Hz applications.
1600 series DIN rail units have variable frequency filter modules, 255 filter steps set by an easy to use DIP switch.
Both versions of DIN Rail rail filters have 2 identical buffered voltage outputs.
DRI version with 4-20mA Outputs
The DRI version adds a flexible configurable 4-20mA output. The filtered voltage is reconverted to a 4-20mA current signal. The output current can be configured EITHER as a current source using the isolated +24V power supply built in the unit, OR as a current sink, where an external +24 supply can be used.
Order as DRI version.
Optional Output Offset
Optional output offset after the filter, before the output buffers, adjustable by multi-turn pot over a +/- 50% of output full scale.
Order as option 'O'.
The 9-30V DC power input in this unit uses conversion methods, please check our page about DC Power.
