Time Delay Relays, R38 Series

Features ±0.1% Repeatability 8-Pin octal plug-in Knob with calibrated scale 2-timing ranges Impact proof dust cover IC hybrid circuitry for timing

RECYCLE TIMING - The first delay period begins when input voltage is applied. At the end of the first delay, or "OFF" period, the internal relay pulls in, and the second delay, or "ON" period, begins. When the second delay period ends, the relay drops out. This recycling sequence will continue until the removal of input voltage. When input voltage is removed, the relay drops out.
