LON Controllers

 

 

 

Every model of the Plexus OPIS Pro L-Series Controllers is completely configurable and/or can use a variety of pre-configured LonMark™ Certified Applications. Whether used in a stand-alone or as an integral device on any LNS Network outstanding performance will always be provided. L-Series Controllers are 100% compatible with almost all other manufacturer’s controllers and most all LNS industry standard Network Management Tools. 

All of the Plexus OPIS Pro L-Series Controllers are built around the Neuron FT-5000 microprocessor and require no commissioning credits. Each controller is built to operate on LonWorks FT-10 twisted-pair. Embedded network update throttling is incorporated in each controller and is adjusted via the Plexus OPIS Pro L-Series Plug-in. 

 

 

Feature Rich

The L-Series Controllers feature rich network interfaces with up to 250 variables. All controller features are adjustable with the L-Series Plug-in or a hand-held device. L-Series Controllers can operate stand-alone or as a networked solution. In a networked environment L-Series Controllers can share information with other controllers peer to peer on a flat line network.

Networks of thousands of devices can easily be created. When monitored with our OPIS- PRO Software Suite, web-based control and monitoring is enabled, large trends, schedules and alarm storage is available. L-Series Controllers can optionally be expanded with a variety of feature add-on boards that enhance the controllers with features such as differential pressure sensing, etc.

LonWorks guidelines are strictly observed and L-Series Controllers are interoperable with other like devices for best network integration and promote the use of the industry’s best products in a network.

The L-Series Controllers are built to the highest quality standards in the United States in our eco-friendly, lead-free technology. All of our Controllers are RoHS compliant and are backed by our two-year limited warranty.

 

OPIS Pro Series Plug-in

The Plexus OPIS Pro L-Series Plug-in is an extremely easy to use graphical user interface for the configuration, monitoring and tuning of any of the L-Series Controllers. The Plug-in simplifies the hardware configuration, control sequences and communication parameters and can be launched as a standalone appliance, from within LonMaker™ for Windows™ or any other similar industry standard network management tool.

 

 

Software features include: 

  • Configurable network variable types
  • 10 PID loops in every controller
  • Configurable I/O properties
  • Network update throttling of each input/output
  • Binding of unused I/O for use by other controllers

 

 

LonMark™ Configurations include: 

  • LonMark™ AHU w/up to 6 stages of heat/cool
  • LonMark™ VAV-8010 v3.4
  • LonMark™ FCU-8020 v3.4
  • LonMark™ RTU-8030 v3.4
  • LonMark™ HPU-8051 v3.4

 

See our LonMark™ Profiles Datasheet for all our configurable applications.  

OPIS Pro L-Series Controllers come in a variety of efficient I/O configurations and can be expanded with additional features.
