SECTION 3 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 Varistor (MOV) circuit protects by shunting 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 connect 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. Diode Circuit Protects External Drive Circuitry from Inductive Voltages Generated when Removing Coil Voltage. Polarity Sensitive. LED Circuit LED Status Lamp Verifies that Power is Being Supplied to the Coil. Ideal for Both AC and DC Applications, Polarity Sensitive for DC Application. The Complete System Solution! Modules Plugging a module into a socket, connects the circuit in parallel with the relay coil. No additional wiring is required. No additional tools are required. The modules fit within the maximum dimensions of both the relay and socket. 3/2 Magnecraft Solution Guide 105A SECTION 3 RC Circuit Snubs Back EMF of Relay Coil.
