MOUNTING D = DIN-rail mounting L = 11 pin plug-in P = 8 pin plug-in SERIES NRU P MOUNTING NRU SERIES 220D INPUT POWER INPUT POWER 24A = 24VAC 48A = 48VAC 110A = 110VAC 220A = 220VAC WIRING DIAGRAM: ORDERING INFORMATION: Control of conductive liquids (tap water, sea water, sewage, chemical solutions, coffee, ice cream, etc.) The relay is energized when the level falls below the low level probe. It de-energizes when the high level probe is reached. The NRU will also control a single level. In this case, a single probe is used and the relay operates when the probe is not immersed. The Max terminal is connected to common with a jumper. In either case, a common electrode is needed if the container is non-conductive. 11 12 14 C R 1 2 3 4 5 6 7 8 9 10 11 1 2 3 45 6 7 8 DNRU PNRU LNRU A1 A2 RR S S S Max C C Max min Max ˜ ˜ min min R S LEVEL Max min R S LEVEL t 0 |
