Page 13: Protecting Inductive Loads
Protecting Inductive Loads When you connect inductive loads to the NI 9485 SSR outputs, a large counter-electromotive force may occur at switching time as a result of the energy stored in the inductive load. These flyback voltages can damage the relay outputs and/or the external power supply. - Page 14 For AC loads—Install a metal oxide varistor (MOV) rated for 30 Vrms or slightly higher. Figure 3.
