Overview

The Littelfuse KSPSP22B solid-state timer module delivers precise, reliable timing for OEM applications requiring compact, maintenance-free operation. Part of the KSPS Series, this factory-programmed module offers a single, fixed time delay adjustable from 1 to 100 seconds via onboard potentiometer, eliminating the need for external timing components. Its microcontroller-based timing circuit ensures repeat accuracy of ±0.5%, providing consistent performance in demanding industrial environments. Designed for space-constrained panels, the KSPSP22B features a robust solid-state output rated for 1A steady-state and 10A inrush current, delivering up to 100 million operations under typical conditions. Unlike electromechanical relays, this module contains no moving parts, eliminating arcing, wear, and mechanical failure. The KSPSP22B operates on 12-120VDC with positive switching, making it ideal for integration into motor control, HVAC systems, lighting control, and process automation. Compatible accessories include the Versa-Pot P1004-95 for remote adjustment, Versa-Knob P0700-7 for panel mounting, and quick-connect terminals P1015-64 and P1015-18 for simplified wiring. With 14 standard functions available across the KSPS Series, this module provides a cost-effective solution for OEMs seeking solid-state reliability without custom engineering. Key applications include delayed activation, interval timing, and pulse generation in manufacturing processes, conveyor systems, and automated equipment. The module's compact form factor and silent operation with minimal heat generation make it suitable for new designs or as a direct replacement for aging electromechanical relays, reducing maintenance costs and downtime.
