Description

The PRLM series is designed for use in non-critical timing

applications. It offers low cost, fixed or knob adjustable

timing control, full 8 A relay output, and onboard LED

indication. The onboard LED indicates whether or not the unit

is timing (flashing LED) as well as the status of the output.

Operation (Delay-on-Make)

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.

Reset: Reset is accomplished by removal of input voltage.

There is no false output when reset during timing.
