Description
The HRDM 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 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.
See accessory pages for
specifications.
