The Siemens 3RT1926-2PA01 is a pneumatic timing relay block designed for precision control in various industrial applications. This component, part of the SIRIUS product family, offers a response-delayed operation ranging from 0.1 to 30 seconds, allowing for adjustable pickup delay time to suit specific requirements. It features a single normally open (NO) and a single normally closed (NC) contact configuration, providing versatility for integration into different control circuits.
Constructed with reliability in mind, the 3RT1926-2PA01 is equipped with screw-type terminals for secure electrical connections in auxiliary and control current circuits. The device is engineered to operate within a protection class of IP20, ensuring that it is safeguarded against solid objects larger than 12.5mm but not against water, making it suitable for use in environments where moisture exposure is controlled.
This pneumatic delay block requires a fuse link for short-circuit protection of the auxiliary switch, specifically a gG 10 A fuse with a short-circuit current Ik of 1 kA according to IEC 60947-5-1 standards. The 3RT1926-2PA01 is a testament to Siemens' commitment to quality and performance, offering a robust solution for time-dependent control tasks in a variety of industrial settings.
