2-channel timer. 1+1 normally open contact potential-free 16A/250V AC. With Astro function. Stand-by loss only 0.03-0.4 watts. From the production week 26/19 with display lighting. Series installation device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. With the patented Eltako-Duplex-Technology (DX), the normally potential-free contacts can still switch at zero crossing when switching from 230V-alternating voltage 50Hz and thus drastically reduce wear. To do this, simply connect the N conductor to the clamp (N) and L to 1(L) and/or 3(L). This results in an additional standby loss of only 0.1 watt. By using bistable relays, there is no coil power loss or heating thereby even when the relay is switched on. Up to 60 timer memory slots are freely distributed to the channels. With date and automatic summer/winter time changeover. Power reserve without battery approx. 7 days. Each memory slot can be occupied either with the Astro function (automati
