METZ CONNECT KRA-M4/1 rozhranový reléový modul, 1 prepínací kontakt, 24 V AC cievka, biely 11061313

In control cabinets and automation systems, a reliable interface relay is essential for switching loads with a low-level control signal. The METZ CONNECT KRA-M4/1 is an interface relay module designed for DIN rail mounting, providing a single changeover contact (SPDT) to switch AC loads up to 250 V. Its 24 V AC coil allows direct control from common building automation or industrial controllers.

Who is it for

This relay module is intended for electricians, panel builders, and system integrators who need a compact, DIN-rail mountable relay to interface between control circuits and power circuits. It is suitable for HVAC, lighting control, and general automation tasks where a 24 V AC control signal must switch a higher voltage load.

Tips

When selecting a relay, ensure the coil voltage matches your control signal and the contact rating exceeds the load requirements. For inductive loads, consider using a snubber or varistor across the contacts to extend relay life.
