The WEIDMULLER TFIS 12-240VUC 2NO SD is a star-delta timer designed for automation engineering applications. It compensates for malfunctions caused by high clock rates by extending short pulses, ensuring reliable identification by downstream control components. This timer offers various timing functions, including make and break delays, clock generator, and star/delta switchover. It features a wide control voltage range (12-240V UC), a continuous current rating of 3A, and utilizes a screw connection for secure wiring. The device is RoHS compliant and suitable for industrial environments requiring precise timing control.
