Description
The HRDI Series combines an electromechanical relay output
with microcontroller timing circuitry. It offers 12 to 230V
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 (Interval)
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.
