Product Description
. . . . . The Network Control Unit (NCU) is a field panel housing electronic modules, terminal blocks, and signal conditioners (pneumatic, line voltage, and electronic) all inside a single enclosure. The NCU is configured to suit a particular application by selecting various control, point interface, and processor modules, and installing them into an appropriate base frame. There are three general application configurations.
The NCU contains the user-programmable main processor-the Network Control Module (NCM)-for supervisory functions over all devices on the local bus, and a combination of the optional Digital Control Module and Point Multiplex Modules to directly control field devices that wire to the NCU termination blocks. This application installs all models of the NCM (101, 102, 401, 200) into standard 1-Slot, 2-Slot, or 5-Slot base frames.
When an application requires the NCM to supervise devices along a trunk, but does not require direct wiring to field devices or the flexibility of interchanging other electronic modules (DCM, XMs), a simpler, streamlined NCM-Only base frame is available. This base frame requires an N1 direct-connect NCM (i.e., the NCM200). Application examples include migration connections (S2, JC/85 Gateway) or when the NCM200 is supervising an application specific controller, such as the fire and safety IFC-2020, security IAC-600, HVAC controllers (AHU, VAV, etc.) or Intelligent Lighting Controller.
As a means to expand the object and control loop capacity of an NCU, this application of the field panel-the Network Expansion Unit (NEU)-is identical to the NCU, except that it lacks an NCM. The NEU provides an intelligent, remote panel to house XMs in the standard 1-Slot base frame or a DCM / XM combination in the standard 2-Slot or 5-Slot base frames. The DCM and XMs directly control field devices, then connect back to an NCU over the local N2 Bus.. Johnson Controls. Johnson Controls. NU-NCM401-0.
