    • 1 Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module’s rated voltage. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit and enter the Info Code induct.
    • 2 Operate time is the time from trigger received by hardware to switch output activation. Certain applications may require additional time for proper settling.
    • 3 The value given for maximum scan rate applies when switching <20 V and 1 A. Refer to the SSR Cycle Frequency Derating by Load Current and Load Voltage figure for other voltages.
