Johnson Controls NU-XBN101-0 Point Multiplex Module, Multiplex Binary (XBN) [Refurbished]

The Point Multiplex Modules (XMs) interface points used for monitoring or supervisory control applications. They are perfect for adding point capacity in applications where the power and sophistication of a DCM is unnecessary. XMs reside in the NCU or NEU. Unlike the DCM, which has universal inputs and outputs characterized by function modules, each XM has a fixed input/output point configuration. All line-voltage relays, manual override controls, and other signal conditioning circuitry are housed within the electronics of the XM. A family of XMs is available, differing only in point I/O mix. Features: plug-in installation and easy commissioning. LED indicators on front of XM show status of each input and output, and status of module itself. built-in self-diagnostics run each time module is turned on. XM can be installed in a 1-slot NEU, 2-slot NCU/NEU, or 5-slot NCU.. Johnson Controls. Johnson Controls. NU-XBN101-0.
