Advantages of the 70-SM Module System

Magnecraft plug in modules are available in many variations allowing coverage for most applications on the market. The Metal Oxide Varis- tor (MOV) circuit protects by shunt- ing potentially damaging electrical spikes away from the relay coil. The Resistor Capacitor (R/C) circuit snubs back Electro Motive Force (EMF) of relay coil. The Diode circuit protects external drive circuitry from inductive voltages generated when removing coil voltage. Finally, the Light Emitting Diode (LED) circuit is to quickly inform the user when power is present at the coil. All of the plug in modules con- nect their respective circuits in parallel with the relay coil. No additional wiring is required, and the modules fit within maximum dimensions of relay and socket.
