Siemens CDN5F-5-100S-5-100M Time Delay Relay

Siemens CDN5F-5-100S-5-100M Time Delay Relay provides dual-range timing in a single device: 5–100 seconds and 5–100 minutes, enabling short- and long-duration delays without swapping modules. As a CDN-series timing relay from Siemens, it is designed to introduce a controlled delay between input and output signals in industrial control circuits. The model name encodes two primary time scales—seconds (5–100 s) and minutes (5–100 min)—allowing compact sequencing logic within automation schemes. Exact electrical ratings, such as coil voltage, contact configuration, and mounting method, are determined by installation requirements and accessory selections; refer to the official product datasheet for precise specifications. This timing relay is suited for applications that require timed interlocks, delayed activation of loads, or staged control in machinery and process lines, helping to manage start-up transients and ensure orderly transitions in control loops. Because it spans short and long delays, it can support startup sequencing, delay interlocks, and timed reset scenarios in conveyors, pumps, and processing lines.
