Eltako NR12-002-3X230V Network monitor No of relay outputs: 2
Line monitoring relay with rotating field monitoring. Stand-by loss only 0.8 watts. Series installation device for mounting on mounting rail (2 TE). For monitoring 230V AC voltage between 1 to 3 phase conductors and the neutral conductor and for monitoring the rotating field (clockwise) in the rotary switch positions 2Ph and 3Ph. In the L1/L2/L3 position, only the rotating field is monitored, regardless of the mains voltage. If L1 fails, the relay will drop immediately without any off-delay. With the lower rotary switch on the front, two pick-up or drop-off voltages can be set and the number of monitored external conductors must be specified. U1: 161V drop-off voltage and 185V pick-up voltage. U2: 196V drop-off voltage and 206V pick-up voltage according to VDE 0100, part 718 (formerly VDE 0108, part 1). LED-display for correct applied voltage. If the polarity is incorrect or if the external conductor is missing, the LED flashes quickly. Off-delay RV can be set with the upper rotary switch from 0.1 to 8 seconds. While the RV time is running, the LED flashes slowly. On-delay 0.5s.This text is machine translated.
