Electrical Specifications LED is lit when there is power to the coil. to EN 61326 Solenoid Indication Standard EMC Qualifications A-Option Direct connected coil shown to the right. Protection network for inductive loads protects the (machine control) switch from high voltages and speeds the de-energizing of the solenoid. D Z-Option Switching Amplifier on Board shown to the right. The circuit on the Z-option is reverse polarity protected. The output is short circuit protected. In case of a shorted solenoid, the amplifier will remove the voltage from it. When the short is removed the...
