The Phoenix Contact EMG 17-REL/KSR- 24/21-21-LC AU is a highly reliable relay module designed to cater to a broad range of applications requiring the switching of small to large loads. This module is equipped with a soldered-in miniature switching relay and features a contact configuration of 2 PDT (double pole, double throw) with a 24 V AC/DC nominal input voltage.
Crafted for durability and performance, the relay module boasts a robust design with contacts made from silver nickel (AgNi) and a hard gold-plated finish, ensuring excellent conductivity and resistance to wear. The module is capable of handling maximum switching voltages of 30 V AC and 36 V DC, with a limiting continuous current of 50 mA. In the event of a damaged gold layer, the module can still manage maximum switching voltages up to 250 V AC/DC and a limiting continuous current of 5 A.
The EMG 17-REL/KSR- 24/21-21-LC AU is designed with safety in mind, featuring safe isolation according to DIN EN 50178 between the coil and contact. The integrated input circuit and interference suppression circuit further enhance the module's reliability and longevity. The relay module's mechanical service life is approximately 2 x 10^7 cycles, making it a long-lasting solution for various industrial applications.
With a compact width of 17.5 mm, height of 75 mm, and depth of 62.5 mm, the module is space-efficient and can be mounted in any position, allowing for flexible installation. The screw connection method ensures secure and straightforward wiring, accommodating a conductor cross-section range from 0.2 mm² to 4 mm² solid and 0.2 mm² to 2.5 mm² flexible.
The EMG 17-REL/KSR- 24/21-21-LC AU is a testament to Phoenix Contact's commitment to quality and innovation, providing a reliable and efficient solution for electrical switching tasks in a variety of industrial environments.
