HRDB Power-Time
Time Delay Relay

Description

The HRDB Series combines an electromechanical relay output with microcontroller timing circuitry. The HRDB
offers 12 to 230 V operation in five ranges and factory fixed, external, or onboard adjustable time delays with
a repeat accuracy of +/-0.5%. The isolated output contact rating allows for direct operation of heavy loads
such as compressors, pumps, blower motors, heaters, etc. The HRDB is ideal for OEM applications where
cost is a factor.

Operation

Function

Input voltage must be applied before and during
timing. Upon closure of the initiate switch, the output
relay energizes. The time delay begins when the initiate
switch is opened. The output remains energized
during timing. At the end of the time delay, the output
de-energizes. The output will energize if the initiate
switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time
delay and output.

V = Voltage L = Load S1 = Initiate Switch
TD = Time Delay R = Reset
t = Incomplete Time Delay

Connection

S1 = Initiate Switch L = Timed Load
UTL = Untimed Load NO = Normally Open
C = Common, Transfer Contact

NOTE: A knob, or terminals 4 & 5 are only included
on adjustable units. RT is used when external
adjustment is ordered. Relay contacts are
isolated. Dashed lines are internal connections.
The untimed load is optional.
