The Finder 8A.88.9.024.1600 is a high-performance OPTA solid-state relay (SSR) expansion module designed to increase the digital I/O capabilities of Finder OPTA programmable logic relays. As part of the advanced Finder OPTA expansion module range, it combines configurable digital and analogue inputs with fast, silent solid-state outputs for applications requiring high switching frequency, long operational life and reliable electronic control.
Designed for seamless integration with Finder OPTA controllers, the module connects via the dedicated AUX expansion port and can be installed alongside additional expansion modules to create scalable automation systems. Its solid-state outputs eliminate mechanical contact wear, making it ideal for applications where traditional relay outputs may be subject to frequent switching cycles.
With 16 configurable digital or 0-10 V analogue inputs and 8 SSR outputs rated at 3 A DC, the 8A.88.9.024.1600 is ideally suited to industrial automation, HVAC systems, machine control, renewable energy systems and advanced building management applications.
Unlike electromechanical relay expansion modules, the Finder 8A.88.9.024.1600 uses solid-state relay technology to provide silent operation, rapid switching and extended service life. The absence of moving contacts eliminates mechanical wear and makes the module particularly suitable for high-frequency switching applications where reliability is critical.
The module integrates directly with Finder OPTA programmable logic relays and supports up to five expansion modules per controller. This flexible architecture allows automation engineers to build scalable control systems while maintaining simple installation and programming.
