Time Delay Relays Dedicated - Delay-on-Make HRDM SERIES Delay-on-Make Timer Description The HRDM Series combines an electromechanical relay output with microcontroller timing circuitry. It offers 12 to 230V operation in five ranges and factory fixed, onboard, or external 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 (Delay-on-Make) Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output relay energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output. Features & Benefits FEATURES BENEFITS Microcontroller based Repeat Accuracy + / - 0.5% Compact, low Allows flexiblility for OEM applications Wiring Diagram cost design Isolated, 30A, SPDT, Allows direct operation of heavy loads: L1 N/L2 NO output contacts compressors, pumps, blower moters, heaters. Encapsulated Protects against shock, vibration, and humidity NO = Normally Open L = Load C = Common, Transfer Contact Accessories NOTE: A knob, or terminals P1004-95, P1004-95-X Versa-Pot 4 & 5 are only included on Panel mountable, industrial potentiometer adjustable units. R is used T recommended for remote time delay adjustment. when external adjustment is ordered. Relay contacts are P1023-6 Mounting bracket 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.
