Analog Signals: Milliamps vs. Voltage

In building automation system applications, the most common types of analog signals are milliamp and DC voltage.

DC voltage signals are most often measured using 0-10V signals, but we also sometimes see 0-5V or 2-10V. The reason for the popularity of the voltage signal is it is easy to troubleshoot and almost all controllers will accept this type of signal.

Integrating Legacy Control Systems

If your facility currently has a legacy control system that needs upgrading but you don’t have the capital budget for a full retrofit, you are likely considering some form of building automation system integration. By integration, we are referring to an approach that would leverage some portion of your existing system while likely changing out some of the higher-level components such as the front-end software and/or parent-level controllers. Integration is a logical choice in this situation but before moving forward with this approach, there are some important elements that you should fully understand.

Computrols adds BTL Listing and Protocol Routing to LX Controller

Building automation system manufacturer Computrols has added a BTL Certification and the ability to route proprietary protocols as BACnet IP points as add-on options to an already feature-rich LX Controller.

The LX Controller has been one of the most dynamic and robust pieces of hardware in the building automation industry for the last 4 years. Boasting an unprecedented lifetime warranty, the LX provides installers and users supreme flexibility with its software-programmable universal I/O and unique two-piece board design. This parent-level controller supports state-of-the-art TLS (Transport Layer Security) and a variety of both open and proprietary communication protocols.

Computrols Donates BAS Components to NTCC

Computrols has recently agreed to donate a number of its building automation system components to the HVAC/R program at Northshore Technical Community College (NOTCC) for student training and education. The contribution comes by way of Computrols involvement with the Building Efficiency for a Sustainable Tomorrow (BEST) Center, a program supporting publicly-funded 2- and 4-year colleges with HVAC/R, controls, building automation, and energy/facilities management curricula.
