The KFD2-SR2-2.W.SM is a signal conditioner used for standstill and rotational direction monitoring. It accepts input frequency pulses and triggers an output when the frequency drops below a selected value. It can also determine rotation direction and has a start-up override feature.
Programming can be done via DIP switches that are accessible on the front of the device. These switches allow you to set the trip values for frequency and select the mode of operation, including standstill monitoring with start-up override or rotation direction monitoring.
The device accepts PNP/push-pull, dry contacts, or NAMUR inputs for monitoring frequency pulses.
The device requires a 24 V DC supply with a power consumption of less than or equal to 1.5 W.
The device provides two relay contact outputs, which can be configured for various monitoring and control applications.
Yes, the device can detect the direction of rotation by using a 90° phase difference between pulse input signals, with a minimum overlapping of 125 µs.
The device can handle a frequency range of up to 2 kHz, with selectable trip values for standstill monitoring.
The device can operate within an ambient temperature range of -20 to 60 °C (-4 to 140 °F).
The device is designed to be mounted on a 35 mm DIN mounting rail according to EN 60715:2001.
The device has a degree of protection of IP20, suitable for indoor use where it is not exposed to water or dust.
