The KRPS Series is a factory programmed time delay relay available with 1 of 15 functions and measures only 2 inches square. The KRPS offers a wide range of fixed, onboard, or externally adjustable time delays. The output relay contacts offer a full 10A rating with complete isolation. Its microcontroller timing circuit provides excellent repeat accuracy and stability. Encapsulation protects against shock, vibration, and humidity. The KRPS Series is a cost effective approach for OEM applications that require small size, isolation, accuracy, and long life. Special time ranges and functions are available.


Operation (Delay on Break)
必须在计时之前和计时期间施加输入电压。 Upon closure of the initiate switch, the output relay energizes. The time delay begins when the initiate switch is opened. 输出在计时期间保持通电。 时间延迟结束时,输出断电。 当施加输入电压时,如果启动开关闭合,输出将通电。
重置: Re-closing the initiate switch during timing resets the time delay. Removing input voltage resets the time delay and output.
