Speed monitor - Speed-/standstill monitoring relay KFU8-DWB-1.D

Speed monitor - Speed-/standstill monitoring relay KFU8-DWB-1.D – Pepperl + Fuchs – 231209 – 4050143062492: Speed monitor KFU8-DWB-1.D, version of the electrical connection=screw connection, rated control supply voltage Us at AC 50 Hz=48..253 V, rated control supply voltage Us at AC 60 Hz=48..253 V, rated control supply voltage Us at DC=20.. 90 V, type of voltage for actuation=AC/DC, with removable terminals=yes, evaluation of the inputs=single-channel, speed monitoring function=yes, standstill monitoring function=no, operating frequency=0.001..12000 Hz, with feedback loop=no, number of outputs, Signaling function, instantaneous, with contacts=2, suitable for safety functions=no, with approval for BG BIA=no, with approval according to UL=no, width=40 mm, height=119 mm, depth=115 mm, This signal isolator monitors the speed over- or falling below a binary signal from a NAMUR sensor or mechanical contact. The input frequency is compared with a reference frequency specified by the user. Exceeding or falling below the speed is signaled via the relay outputs. The line fault monitoring of the field circuit is displayed via a red LED and a relay output. The start-up delay sets the relay outputs to the value preselected by the user of up to 1000 s. The device can be easily programmed using the control buttons on the front of the device
