2961105 Phoenix Contact REL-MR-24DC/21 Jednoduché relé 1CO

The Phoenix Contact REL-MR- 24DC/21 is a plug-in miniature power relay with 1 changeover contact and a 24 V DC coil input, designed for switching loads up to 6 A at up to 250 V AC/DC. It provides safe isolation between coil and contact side, verified by a 4 kV AC test voltage, and accepts a wide input range of 14.4 V DC to 66 V DC. Rated for -40°C to 85°C, the relay mounts in any orientation and installs in rows with zero spacing.
