Time Delay Relays Dedicated - Interval HRDI SERIES Interval Timer Description The HRDI Series combines an electromechanical relay output with microcontroller timing circuitry. It offers 12 to 230V operation in five ranges and factory fixed, external, or onboard adjustable time delays with a repeat accuracy of 0.5%. The output contact rating allows for direct operation of heavy loads, such as compressors, pumps, blower motors, heaters, etc. This series is ideal for OEM applications where cost is a factor. Operation (Interval) Upon application of input voltage, the time delay begins. The output relay is energized during the time delay. At the end of the time delay, the output de-energizes and remains de-energized until input voltage is removed. Reset: Removing input voltage resets the time delay and the output. Features & Benefits FEATURES BENEFITS Microcontroller based Repeat Accuracy +/- 0.5% Wiring Diagram Compact, low Allows flexiblility for OEM applications cost design L1 N/L2 Isolated, 30A, SPDT, Allows direct operation of heavy loads: NO output contacts compressors, pumps, blower moters, heaters. C = Common, Transfer Contact Encapsulated Protects against shock, vibration, and humidity. NO = Normally Open L = Load Accessories NOTE: A knob, or terminals 4 & 5 are only P1004-95, P1004-95-X Versa-Pot included on adjustable Panel mountable, industrial potentiometer T units. R is used when recommended for remote time delay adjustment. T external adjustment is ordered. Relay contacts P1023-6 Mounting bracket are not isolated. The 90 orientation of mounting slots makes installation/removal of modules quick and easy. P0700-7 Versa-Knob Designed for 0.25 in (6.35 mm) shaft of Versa-Pot. Semi-gloss industrial black finish.
