Model SM series are potentiometer setting meter relays with dual Hi & Lo settings. The setters are multi-turn resistive potentiometers as pre-set buffers which settings are able to be read directly in display for switch selection. The input functions of the units are of wide varieties & ranges, including many parameters of industry process and power system as DCV, ACV, DCA, ACA, DC rate, and temperature.
