(45.2) ➛ ➛ ➛ Outline Dimensions Wiring Diagrams – Bottom Views (pins numbered clockwise from keyway) * If control switch is closed when power is applied, relay will immediately energize. A 50 millisecond minimum switch closure is required. 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. ** Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”. + _ INPUT (DC POLARITY INDICATED) Fig. 1 8 Pin EXTERNAL RESISTOR INPUT (DC POLARITY INDICATED) Fig. 2 11 Pin Fig. 3 11 Pin AC INPUT EXT SWITCH* + _ + - Delay on Operate Models Voltage Time Adjustment Wiring Dia.
