Unison 901 ZDA 48 25 01 AL5 Solid State Relay | DC to AC SSR | 25A Output Relay

Product Description

The Unison 901 ZDA 48 25 01 AL5 is a high-performance Solid State Relay (SSR) designed for reliable switching of AC loads using a DC control signal. With a load current rating of 25A, this SSR provides fast, silent, and wear-free switching, making it an ideal replacement for conventional electromechanical relays in industrial automation systems.

Built with solid-state technology, the relay offers excellent switching life, high reliability, and resistance to vibration and mechanical wear. It is widely used in temperature control systems, industrial heaters, packaging machinery, and automation equipment where frequent switching is required.

What is it?

The Unison 901 ZDA 48 25 01 AL5 is a DC-to-AC Solid State Relay that allows low-voltage DC control signals from PLCs, controllers, and automation systems to switch high-power AC loads safely and efficiently. Unlike conventional relays, it contains no moving parts, resulting in longer operational life and maintenance-free performance.
