Solving your relay requirements since 1922 HDOD Series Delay-On-Dropout Time Delay Relay Solid state CMOS digital circuitry True delay on dropout: Timing cycle after power removal DPDT (2 form C) isolated 4 ampere relay contacts Built-in timing adjust potentiometer Numerous models from 0.1 seconds to hours Timing Mode Upon the application of input voltage the relay immediately energizes. The timing cycle begins when input voltage is removed. When the timing cycle is complete, the relay will de-energize TIMING DIAGRAM: CONTACT INFORMATION Arrangement: 2 form C (DPDT) Contact material: Gold Clad Silver Alloy Rating: Maximum Switching Power - 1000 VA, 90W (Resistive); Maximum Switching Voltage - 250V AC, 48V DC Maximum Switching Current - 4 Amperes Nominal Switching Capacity - 4A 250V AC, 3A 30V DC UL/CSA Rating - 4 A 1/20 HP 125, 250V AC, 3A 30V DC Expected Life @ 25C Mechanical: 100 Million operations Electrical 100,000 operation at 4A 250V AC 200,000 operations at 3A 30V DC ENVIRONMENTAL INFORMATION temperature Range: Ambient: - 40C to 65C (-40 to +149F) OUTLINE DIMENSIONS Solving your relay requirements since 1922 Timing Specifications Fixed timing: 0.1 seconds to hour, tolerance 5% consult factory for availability.
