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 wiper time function after the control contact has been opened, 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 of which can be loaded with 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 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 supply voltage is 24 VDC/24-240 VAC. The cable is connected using screw terminals.
