On/Off Delay Relay
The Model 339 On/Off Delay Relay offers reliable control for industrial applications requiring precise timing. Its dual delay functionality, providing both on-delay and true off-delay, enhances operational sequencing and system synchronization. A key advantage is that no power is required during the off-timing cycle, which contributes to energy efficiency in continuous operations. Separate adjustments for each delay allow for granular control and precise system integration, accommodating diverse application requirements. With standard relay wiring, installation is straightforward, minimizing setup time. The DPDT contact configuration and 10A at 120VAC resistive rating ensure robust switching capabilities for various loads. This unit is designed for consistent performance across multiple supply voltages, from 24VAC/DC to 240VAC/DC. Its operational integrity is further supported by a 5-year unconditional warranty, ensuring long-term operational stability and reduced maintenance concerns.
