High and Low Side Drivers
When connecting to the VSIM as a method of controlling an electrical device, it is important to
know how a device is controlled. For example, some output circuits are low-side drivers, while
others are high-side drivers. This is how the module is designed, and nothing that can be changed
through programming or settings. Each driver inside the module is part of the control board, and
designed for circuit protection.
In all cases, the VSIM should not be connected directly to an output device, but to a relay which is
wired into that device. A relay is designed to use a smaller current than most outputs, and is used
to allow this smaller current to control a larger current.
