The Finder 19.91.9.024.4000 is a compact and robust power relay module from the Finder 19 Series, designed for switching additional electrical loads in automation and lighting-control installations. It is specifically intended for use as an output module with compatible Finder control equipment, including the Finder 11.91 twilight switch.
This relay module provides a 1CO changeover contact rated at 16 A and uses a 24 V DC operating supply. Its AgSnO2 contact material supports reliable switching of demanding electrical loads, while the monostable relay operation makes it suitable for controlled output switching in building automation and electrical distribution systems.
With a maximum switching voltage of 250 V AC, an AC1 switching capacity of 4000 VA and a compact 17.5 mm DIN-rail mounting width, the 19.91.9.024.4000 provides a practical way to extend lighting-control and automation systems with an additional high-current relay output.
Power relay modules such as the Finder 19.91 provide an electrically controlled switching interface between an automation device and higher-current electrical loads. The 19.91.9.024.4000 can be used to add a relay-controlled output to compatible systems while keeping low-voltage control circuitry separate from the switched load.
The module is particularly suited to extending Finder lighting-control installations, including applications where an additional lux-controlled lamp group is required with the Finder 11.91 twilight switch. Its DIN-rail construction allows straightforward installation alongside other modular control equipment inside electrical distribution boards.
