Pulse inputs for NPN, PNP or voltage signals Built-in supply for external sensor 16 metering ranges, switch selectable Galvanically isolation between supply, input and output Current, voltage or relay output DC supply or AC supply voltages up to 230 VAC Made in accordance with the and EMC regulations Hysteresis: Relay version: Metering ranges: Pulse/pause ratio: 5% 16 Selectable ranges from 0-100 p.p.m. to 0-20000 Hz. min 10% at max speed for each range (min 15µsec. at range D,E and F) Front view: The C-macâ converter, type LR10 is used for speed monitoring, where the input signal comes from a contact, a proximity sensor, a flow transducer or similar. The unit is supplied with a 24 VDC, max. 25 mA output, which can be used to supply an external proximity sensor. The unit is supplied with either analogue or relay output. By means of a rotary switch on front of the unit you can select between 16 different metering ranges from 0-100 p.p.m. to 0-20000 Hz. With analogue outputs you use another switch to select the output range (0-20 / 4-20 mA or 0-10 / 2-10 V) and to enable fine-adjustment of the metering range With the fine-adjustment you can select any range between the nominal range lower than the actual range up to maximum of the actual range. With relay output you use the switches to select the relay functions (relay on / relay off) The analogue output level is updated at each input pulse (at high speed ranges 10 times per second), which ensures a quick reaction and a stable output signal, even at very low input frequencies.
