VLX Controller; EXP Point Modules: EXP-1048, EXP-10120, and EXP-2200
|
Product Description:
|
The Alerton VLX is a programmable primary controller that can be configured with up to 176 modular I/O. The VLX supports up to eight expansion modules (EXPs) that offer a mix of universal 12-bit inputs, binary triac outputs, and 8-bit analog outputs. The VLX is BACnet/IP capable and can be connected directly to an IP network for communication across local or campus networks. The VLX communicates using BACnet/Ethernet and/or BACnet/IP. When communicating using BACnet/IP the VLX can act as a BACnet Broadcast Management Device (BBMD) and communicate with up to 31 other BBMDs. The VLX can also be connected to the secondary MS/TP network if needed. A VLX has the additional capability of managing up to 10 MS/TP devices (including schedules, alarms, and trendlogs).

Product Application(s):
|
EXP Modules are available in three models:
EXP-1048 has ten 12-bit universal inputs, four binary triac outputs (each with hand-off-auto switch), and eight 8-bit analog outputs (each with hand-off-auto switch and trim-pot).
EXP-10120 has ten 12-bit universal inputs, twelve binary triac outputs (each with hand-off-auto switch), and no analog outputs.
EXP-2200 has twenty-two 12-bit universal inputs and no binary or analog outputs.designed specifically for larger, more complex point applications such as chiller plants, large air handling units, and other critical environments with numerous control points. It may also be used in applications where all wiring is at a central location.

|
Clock Type
|
|
Clock Synchronization
|
Synched up via standard BACnet Time_Synchronization message by OWS, or by any device which can transmit standard BACnet Time_Synch.
|
Volatile Memory (RAM) Capacity
|
32MB DRAM
|
Volatile Memory (RAM) Uses
|
|
|
Is Volatile Memory Supported By Battery?
|
No - Battery maintains internal clock only
|
Battery Type(s)
|
Internal replaceable 3v lithium coin-cell
|
Battery Life
|
Internal 3v lithium coin-cell has a standby life of ten years.
|
Backup Battery Operating Time
|
Internal 3v lithium coin-cell provides up to 1.5 years cumulative real-time clock without AC or battery power.
|

|
Additional Information
|
|
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly
impact system performance.
|
Can trend data be stored in this controller?
|
Yes
|
How many total trend values can be stored?
|
Up to 200 trendlogs can be stored consisting of 1 point per log and 256 samples per point (for a total of 51,200 stored samples per controller)
|
What is the controllers role in trending?
|
Programming resident within VLX gathers and stores trend data on-board. At set intervals, data is sent by the VLX to a workstation for archival.
|
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
|
|
When full, does controller automatically send up trend data, overwrite data, or stop logging data?
|
If controller trend data buffer fills before being called by archive workstation, old data is overwritten.
|
Programming Method(s)
|
Alerton VisualLogic graphical programming. Optional menu-based set-up/configuration can be performed.
