The KRDS Series is a compact time delay relay measuring only 2 in. (50.8 mm) square. Its microcontroller timing circuit provides excellent repeat accuracy and stability. Encapsulation protects against shock, vibration, and humidity. The KRDS Series is a cost effective approach for OEM applications that require small size, isolation, reliability, and long life.
Operation (Single Shot)
必须在计时之前和计时期间施加输入电压。 Upon momentary or maintained closure of the initiate switch, the output relay energizes for a measured interval of time. At the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing has no affect on the time delay. 当施加输入电压时，如果启动开关闭合，输出将通电。
重置: Reset occurs when the time delay is complete and the initiate switch is opened. 丢失输入电压会复位时间延迟和输出。
