Description
DescriptionDescription
The PRLM Series is designed for use in non-critical timing applications. It offers low cost knob adjustable
timing control, full 10 A relay output, and onboard LED indication. The knob adjustment provides a guaranteed
time range of up to 10 minutes in 6 ranges. The onboard LED indicates whether or not the unit is timing (flashing
LED) as well as the status of the output.

The time delay is initiated when input voltage is applied.
LED flashes during timing. At the end of the delay period,
the output contacts energize. LED is on steady after
the unit times out.
