Time Delay Relays Dedicated - Recycle HRDR SERIES Recycling Timer Description The HRDR Series combines an electromechanical relay and microcontroller timing circuitry. It offers 12 to 230V operation in five ranges and factory fixed, onboard or externally adjustable time delays with a repeat accuracy of 0.5%. The high switching capacity of the output contacts allow for direct control of heavy loads like compressors, pumps, motors, heaters and lighting. A bypass/reset switch option allows operator to interrupt normal recycling sequence and energize output relay. An excellent choice for OEM applications. Operation (Recycling with Reset Switch) Upon application of input voltage, the ON time T1 begins and output relay energizes. At the end of the ON time, the output relay de-energizes and the OFF time T2 begins. At the end of the OFF time, the output relay energizes and the cycle repeats as long as input voltage is applied. Some recycling timers have the OFF time as the first delay. Reset: Removing input voltage resets output and time delays, and returns sequence to the first delay. Wiring Diagram Bypass/Reset Switch: Closing the normally open bypass/reset L1 N/L2 switch energizes the output relay and resets the time delays. NO = Normally Open Opening the switch restarts recycling operation with the S1 = Reset Switch first delay. C = Common, Transfer Contact L = Load Features & Benefits Terminals 4 & 5 and/or 7 & 8 FEATURES BENEFITS are only included on externally adjustable units. Relay Microcontroller based Repeat Accuracy + / - 0.5% contacts are non-isolated. Compact, low R is included when external Allows flexiblility for OEM applications T cost design adjustment is ordered. Isolated, 30A, SPDT, Allows direct operation of heavy loads: Terminal 6 is included when NO output contacts compressors, pumps, blower moters, heaters. Bypass/Reset is selected. Encapsulated Protects against shock, vibration, and humidity Independent adjustment Provides greater flexibility of timing options of On and Off delays Bypass/Reset Allows operator to interrupt the timing sequence switch option and energize the output relay Ordering Information INPUT OPERATING BYPASS / RESET MODEL EXTERNAL ADJUSTMENT T1 ON TIME T2 OFF TIME VOLTAGE SEQUENCE OPTION HRDR121A4R 12VDC Both time onboard adj 1 - 100s On time first 1 - 100m Yes HRDR321A4R 24VDC Both time onboard adj 1 - 100s On time first 1 - 100m Yes HRDR322B2R 24VDC Both time onboard adj 10 - 1000S Off time first 10 - 1000S Yes HRDR330A0R 24VDC Both time external adj 0.1 - 10s On time first 0.1 - 10s Yes HRDR331A1 24VDC Both time external adj 1 - 100s On time first 1 - 100s No HRDR411SB30MR 120VAC Both times fixed 1s Off time first 30m Yes HRDR431A1R 120VAC Both times external adj 0.1 - 100s On time first 0.1 - 100s Yes If you dont find the part you need, call us for a custom product 800-843-8848 2016 Littelfuse Protection Relays & Controls Rev: 1-A-062116 www.littelfuse.com/hrdrTime Delay Relays Dedicated - Recycle HRDR SERIES Accessories Specifications Time Delay P1004-95, P1004-95-X Versa-Pot Range 100ms - 1000m in 6 adjustable ranges or fixed Panel mountable, industrial potentiometer Repeat Accuracy 0.5% or 20ms, whichever is greater recommended for remote time delay adjustment.
