Harmony Time. Electronic time relay for controlling automation applications with a width of 22.5 mm for mounting on a top hat rail. It has a time function of a pulsed switch-on, which also offers the option of restart control. The time range is 0.05 s - 300 h. A relay changeover switch with a load capacity of up to 8 A switches at the output. The settings are made using a control element on the front, which can be protected against changes under a transparent cover. An illuminated scale arrow makes it very easy to see the setting of the potentiometers, even from a distance. The diagnostic switch on the front enables the output relay to be switched on to test the entire application, particularly with long time functions. The diagnostic switch is automatically reset when the transparent cover is closed. LED displays provide information about the status. The wide-voltage power supply (24-240 VAC/DC) enables universal use. The cable connection is made using screw terminals.
