Outline Dimensions Wiring Diagrams (Bottom Views) (pins numbered clockwise from keyway) * Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”. ** Important: A dry circuit switch is recommended. A “dry circuit” switch is one rated to reliably switch currents of less than 50mA. Use of a switch rated for other than dry circuit may result in failure of the time delay relay to function properly.
