Wechsler potential-free 10A/250 V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. Standby loss only 0.4 watts. Rail-mounted device for installation on DIN-EN 60715 TH35 mounting rails. 1 division unit = 18 mm wide, 58 mm deep. With the patented ELTAKO duplex technology (DX), the normally potential-free contacts can still switch at the zero crossing when switching 230 V alternating current 50 Hz, thereby drastically reducing wear. Simply connect the neutral conductor to terminal (N) and the live conductor to 15 (L). This results in an additional standby loss of only 0.1 watts. Supply and control voltage 230V AC. Times between 0.1 seconds and 40 hours are adjustable. Function F (description pages 13-22) RV = fallback delay AV = response delay TI = pulse generator starting with pulse TP = pulse generator starting with pause IA = pulse-controlled response delay (e.g., automatic door opener) EW = turn-on wipe AW = turn-off wipe ARV = response and fallback delay ON = permanent ON OFF = permanent OFF. The LED under the large rotary switch indicates the contact position during the timing process. It blinks as long as the working contact 15-18 is open (15-16 closed) and lights steadily as long as the working contact 15-18 is closed (15-16 open). The time base T is set with the middle detent rotary switch T. Base values are available at 0.1 seconds, 0.5 seconds, 2 seconds, 5 seconds, 1 minute, 2 minutes, 5 minutes, 1 hour, 2 hours, and 4 hours. The total time is calculated by multiplying the time base by the multiplier. The multiplier xT is set with the upper detent rotary switch xT and ranges from 1 to 10. Thus, times between 0.1 seconds (time base 0.1 seconds and multiplier 1) and 40 hours (time base 4 hours and multiplier 10) can be set. The maximum load can be used from a delay or pulse time of 5 minutes.
