Since this is much less than the end-to-end resistance of a zener barrier, it may be necessary to specify a monitor intended for use without a barrier. Please follow the advice of the monitor manufacturer.
Transfer characteristics

DeviationDC transfer error (with 10 kΩ load) < 10mV
After calibrationadditional error with AC superimposed is ±5 mV at 20 °C (68 °F) at any point within the span, provided that the alternating component of the input voltage is not excessive, e. g.
- square waves (0 ... 20 kHz): 5 Vpp
- sine waves (0 ... 20 kHz): the full span of 20 Vpp (= 100 g peak acceleration at 100 mV/g) is acceptable.

Details: KFD2-VR4-Ex1.26

This isolated barrier is used for intrinsic safety applications. It provides a floating output to power a vibration sensor (e. g., Bently Nevada) or accelerometer in a hazardous area and transfers the voltage signal from that sensor to the safe area.

The device is designed to provide a voltage or current supply to the vibration sensor. Depending on connection the barrier provides 3.6 mA, 5.3 mA, or 8.9 mA supply current for 2-wire sensors, or 18 V at 20 mA for 3-wire sensors.
