SZR Multifunctional Time Relay

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, SZR Multifunctional Time Relay is developed for applications requiring accurate time delay and automatic control functions. The relay provides flexible timing control solutions for electrical circuits, helping equipment achieve delayed start, delayed stop, interval operation and sequence control.​

Compared with conventional single-function time relays, SZR provides more application flexibility by integrating multiple timing modes into one device. Engineers can select suitable timing functions according to different control requirements, reducing system complexity and improving control efficiency.​

With compact modular structure and reliable relay output, SZR can be easily installed in control cabinets, distribution panels and industrial automation systems. It is widely used in motor control, production equipment, lighting systems, HVAC equipment and other electrical control applications.​
