The Murphy 12V SS300-AD-12 is a single set point speed switch with SPDT relay dry contact output. The trip point is set by a potentiometer. An LED indicates when the signal source is present. A second LED turns on when the trip point is reached. An optional time delay is on board to delay operation of the relay for 2-6 seconds after the set point has been reached. This adjustable differential model SS300-AD-12 can be adjusted to change the speed range over which the pull-in and drop-out differential of the relay will operate. A typical application is to insure that engine speed is above a minimum RPM before applying a load but allows a drop in speed of several hundred RPM without disconnecting the load.
The SS300-AD-12 speed switch is intended for installation within a weather- proof enclosure to protect it from rain, dust, etc.
