This document provides technical details for the K303 delay timer module. It includes a schematic overview of off-delay and on-delay configurations, a comparison table of K303 performance metrics across various module types (K303, K374, K376, K378), and guidance on using the timer with fixed delay elements or rheostat control. Additionally, it explains how to mount control modules for calibration and how to configure K303 sections as an oscillator to achieve longer delays.
