Input Point Expanders
VBUS
• VBUS is an internal communication bus that related VBUS modules are used with. The VBUS is not intended for external use. It
has been designed to be used in a protected enclosure with adjoining interconnection between modules in the same enclosure.
It communicates with the main control over the Module Bus (SNAPP) which is for external communications.
• VBUS and VBUS modules allow the system to be expanded without adding additional modules on the main Module Bus
(SNAPP).
