TE Connectivity / Agastat Brand SCERW21AEA Discrete Plug-in Time Delay Relay
The TE Connectivity SCERW21AEA is a specification-grade discrete plug-in time delay relay designed for a variety of industrial applications. Its true off-delay timing mode cancels the delay period if the operating voltage is reapplied before the delay expires. The relay offers multiple timing ranges, from 0.1 seconds to 10 minutes, and provides excellent repeat accuracy. It is suitable for applications requiring precise timing control and reliable operation in demanding environments. The relay's robust construction and 10A SPDT or 5A DPDT output contacts ensure dependable performance.
