Siemens 3RT1926-2CH21 Solid-State Timing Relay (SIRIUS Series)
Description:
The Siemens 3RT1926-2CH21 is a precision electronic timing relay from the robust SIRIUS series, designed to deliver reliable on-delay timing control for automation and motor control systems. This solid-state timer module supports a time setting range from 0.5 to 10 seconds and features a single normally open (NO) output with integrated varistor protection, making it ideal for precise delay operations in industrial control cabinets and contactor assemblies.
Built for easy integration, the 3RT1926-2CH21 timing relay mounts directly to compatible Siemens contactors (size S0–S3), allowing compact, space-saving installation in machinery and control panels. Rated for 90–240 V AC/DC operating voltage, this module provides consistent performance across a wide range of applications.
