Overview

The ABB NS22ES-20 is an AC-operated relay designed for auxiliary and control circuit switching in industrial applications. This model features 2 Normally Open (NO) and 2 Normally Closed (NC) contacts with spring return, ensuring reliable operation in demanding environments. The relay operates on 24V AC (50/60 Hz) control voltage and is equipped with spring terminals for quick, secure wiring. Designed for DIN rail mounting, the NS22ES-20 is part of ABB's NS..S series, known for mechanically linked auxiliary contacts and modular accessories for expanded functionality. Ideal for motor control, automation systems, and process instrumentation where dependable switching is critical. The spring terminal design eliminates the need for screw tightening, reducing installation time and minimizing wiring errors. Compatible with standard industrial control systems, this relay provides a compact, modular solution for control circuit applications requiring 2NO/2NC contact configurations. The device's spring return mechanism ensures contacts return to their default state upon de-energization, enhancing safety and reliability in control applications.
