Description

The HRDR Series combines an electromechanical relay and microcontroller timing circuitry. It offers 12 to

230 V 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. Bypass/reset switch option allows operator to

interrupt normal recycling sequence and energize output relay. An excellent choice for OEM applications.

Operation

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.

Bypass/Reset Switch: Closing the normally open

bypass/reset switch energizes the output relay and

resets the time delays. Opening the switch restarts

recycling operation with the first delay.

Function

Recycling w/Reset Switch

V = Voltage S1 = Reset Switch

L = Load R = Reset T1 = ON Time

T2 = OFF Time

= Undefined time

Connection

Mechanical View

Note: Terminals 4 & 5 and/or 7 & 8 are only

included on externally adjustable units.

NO = Normally Open S1 = Reset Switch

C = Common, Transfer Contact L = Load

Relay contacts are non-isolated. RT is included

when external adjustment is ordered. Dashed

lines are internal connections. Terminal 6 is

included when Bypass/Reset is selected.
