Surge Suppressor Diode Module - DC Control 12-250VDC, Plug-in, coil mounted, for use with CA7-9C..43C (with conventional DC control)

Features:
• Surge Suppressors are used to suppress the high voltage spike that is generated when a relay or contactor coil is de-energized.
• The electromagnetic field collapsing across the coil generates a voltage spike in the wires of the control system.
• Without the suppressor, the surge can reach 8 to 10 times the rated coil voltage and can propagate through the system causing electronic controls to go to unwanted states and filling counters with erroneous numbers
• The Diode Suppressor suppresses the DC voltage from a DC Voltage coil very smoothly by recirculating the voltage through the coil.
• The energy caused by the voltage spike would be dissipated by the coil itself. Because of this, the coil drop out time is usually increased from 3 to 10 times the usual drop out time when using a diode type of suppressor.
• Surge protection module Electrical Function, Diode Voltage type for actuating DC Rated control supply voltage Us, at DC12-250 V.
