EMAS RR3ZTC02 is a double time set analogue electronic relay with 24 V AC/DC to 230 V AC operation, a 0.06 second to 10 hour timing range and a 10 A / 250 V AC changeover output for cyclic industrial control applications.
£42.92
The EMAS RR3ZTC02 is a compact and versatile double time set analogue electronic relay designed for cyclic timing and multi-stage flashing applications in industrial automation and electrical control systems. As part of the EMAS RR3 electronic relay series, it provides independently adjustable timing control in a practical rail-mounted format suitable for machinery and control panels.
This electronic time relay is designed for applications requiring repeated timed switching with separate timing periods. Its double time set functionality makes it particularly suitable for flashing, cyclic operation and automated equipment sequences where different ON and OFF periods are required. Analogue adjustment provides straightforward configuration without complex programming.
With an operating voltage range of 24 V AC/DC to 230 V AC and an adjustable timing interval from 0.06 s to 10 h, the RR3ZTC02 provides considerable flexibility for industrial control applications. Its 1CO changeover relay output is rated at 10 A / 250 V AC, providing dependable switching for contactors, signalling equipment and auxiliary control circuits.
Double time set relays such as the EMAS RR3ZTC02 are designed to provide repetitive switching using separately controlled timing periods. This allows equipment to alternate between ON and OFF states automatically, making the relay particularly useful for flashing indicators, cyclic machinery functions and repetitive process control.
The RR3ZTC02 combines a broad timing interval with universal AC/DC control voltage compatibility and a robust changeover relay output. Its compact rail-mounted housing, analogue adjustment and long operating life make it a practical solution for panel builders, machine manufacturers and industrial automation engineers.
