Johnson Controls FM-IBN101-0 Metasys IBN Input Binary Function Module [Refurbished]

The Input Binary (IBN) Function Module is a signal conditioning device that interfaces incoming field signals to the DCM. The IBN converts field data from two different binary inputs to a voltage for use by the DCM. The inputs are available as either: Binary (open/closed) state of dry contacts. High/low input voltage levels. The IBN Function Module plugs into any of the top ten slots associated with the DCM. Figure 1 shows typical function module locations in the NCU.. Johnson Controls.
