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 the time function symmetrical response and release delay (same time for both delays), which also offers the option of summing up contact interruptions. The time range is 0.05 s - 300 h. Two relay changeover switches switch at the output, each with a load of up to 8 A. The second relay output can switch synchronously with the first output or report that the device is ready for operation. The settings are made using the control element on the front, which can be protected against changes under a transparent cover. The 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 via screw terminals.
