Description
The HRDI Series combines an electromechanical relay output with microcontroller timing circuitry. It 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 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
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.
