Electronic Timer Relay (ETR) is a 22.5-mm narrow module which allows the user to adjust all timingfunctions via front potentio-meter and DIP switch array. The relay also features a broad time range of 40 msec to 2,500 sec, and "universal" input voltage of 18 to 285V ac/dc. The ETR's industrial housings are DIN-rail-mountable, and single lines are securely connected from a screw connection technology.
