Overview

The Littelfuse KSPSP22B, part of the KSPS Series, is a factory-programmed solid-state timer module designed for OEM applications requiring precise and reliable timing. This module offers a single, fixed time delay that can be externally or onboard adjustable, providing flexibility in system integration. Its microcontroller-based timing circuit ensures excellent repeat accuracy of ±0.5% and superior stability, eliminating the wear, arcing, and moving parts associated with electromechanical relays. The KSPSP22B features a robust solid-state output rated for 1A steady-state and 10A inrush, delivering an impressive typical operational life of 100 million cycles. Encapsulation provides comprehensive protection against shock, vibration, and humidity, meeting stringent industrial standards such as IEC 60068-2-6, IEC 60068-2-27, and IEC 60068-2-30. This compact form factor is ideal for space-constrained OEM panels. The KSPS Series is available in 14 standard functions, making it a cost-effective solution for various industrial control needs. Compatible accessories, including the Versa-Pot potentiometer (P1004-95) for remote adjustment, Versa-Knob (P0700-7), and quick-connect terminals (P1015-64, P1015-18), further enhance its integration capabilities. Key applications include manufacturing processes, HVAC systems, lighting control, motor control, and process automation, supporting functions like delayed activation, interval timing, and pulse generation. The KSPSP22B meets critical certifications including UL 508, CSA C22.2 No. 14, and CE (EN 61000-6-2, EN 61000-6-4). It operates silently with minimal heat generation and offers robust EMI immunity. This solid-state timer is an excellent choice for new designs or as a maintenance-reducing replacement for older electromechanical relays. It is manufactured in the USA and is part of Littelfuse's extensive industrial control portfolio.
