Parker Vansco VMM1210 - Inductive Load Protection

34 VMM1210
Outputs
This detection is programmable on or off on a module by module basis.
 If programmed as on for the module, the detection process is programmable as
active only at power up, or as active on a periodic basis with adjustable time
between checks.
 If programmed as on for the module, certain outputs can be programmed as
ignored in the detection scheme to prevent false readings on high resistance or
high voltage drop loads such as LED lights.
4.3.5. Inductive Load Protection
Outputs OUTPUT1_10A_HS to OUTPUT8_10A_HS are internally protected
against 600V inductive loads as outlined in the “SAE J1455 Joint SAE/TMC
Recommended Environmental Practices for Electronic Equipment Design”
specification.
Inductive loads which produce a greater voltage or energy content than that
shown in the “SAE J1455 Joint SAE/TMC Recommended Environmental
Practices for Electronic Equipment Design” specification require the use of
external back EMF/Transient suppression diodes when connected to any of the
high-side 10 A outputs.
Outputs OUTPUT9_3A to OUTPUT10_3A must be externally protected with
back EMF/Transient suppression diodes if connected to an inductive load of any
kind.
