Appendix C.1.1 Versatile Interface Board Overview
The Versatile Interface Board (VIB) is designed to provide real-time status feedback and control of
the Liebert FS. The VIB has 16 digital outputs (isolated, dry Form C contacts) and three digital
inputs (optical isolator) that provide the user with information about the operational mode and state
of charge of the Liebert FS, as well as the ability for the user to start the system, stop the system and
clear alarms.
The VIB consists of the following components:
• 12578 - Auxiliary I/O Interface Board
• 11516 - User Interface Board (UIB)
• 12781 - Cable Assembly
• Mounting hardware
Figure 116 shows the two main electrical components of the VIB.
