Installation time relay suitable for installation in distribution boards on 35 mm standard rail - width 17.5 mm. Front-mounted, lockable rotary switches for function and time range selection, operable with a screwdriver. The indicators for the switching state of the output relay (1 potential-free changeover contact) and the operating voltage (flashing during the time interval) ensure constant monitoring of the operational status. The robust control contact allows for switching parallel loads, such as contactors, relays, or indicator lights. The offset connection terminals are supplied with non-loss screw terminals. The universal operating voltage and the wide time range of 50 ms - 100 h open up a variety of applications with a time accuracy of ±0.5%.
