KRD3421A工业自动化与控制的延时继电器规格书PDF中文资料

描述 Description

The KRD3 Series measures only 2 in. (50.8 mm) square.Its

solid-state timing circuit provides excellent repeat accuracy and

stability. Encapsulation protects against shock, vibration, and

humidity. The KRD3 Series is a cost effective approach for OEM

applications that require small size, isolation, reliability, and

long life.

Operation (Recycling Flasher - ON Time First)

Upon application of input voltage, the output energizes and

the T1 ON time begins. At the end of the ON time, the output

de-energizes and the T2 OFF time begins. At the end of the

OFF time, the output energizes and the cycle repeats as long as

input voltage is applied.

Reset: Removing input voltage resets the output and time

delays, and returns the sequence to T1 ON time.
