Alerton’s VLCA-1688 is an advanced application controller (AAC; BTL listing is pending) with a high resolution 12-bit A/D; D/A converter and new, 32-bit processor and real-time clock that supports its own schedules, trendlogs and alarms. The VLCA-1688 includes monitored on-board Hand-Off-Auto (HOA) switches, Ethernet or MS/TP connectivity, and additional math functions beyond the standard VLC.

Do you need the IMSL libraries? Fortran 66 manual. Well, that was replaced by Digital Visual Fortran 5.0 more than ten years ago. If not, you can save a lot of money. There is not a discounted upgrade from MSFPS. The current pricing for Intel Visual Fortran Standard Edition is $499 (suggested retail).

May 5, 2017 - If you dig into any BAS programming software you will begin to notice that all. Essentially logic blocks are visual (blocks) of code or actual code that tells. Back when I was programming Alerton controls you would literally.

It also leverages new DDC Function blocks such as an astronomical clock and wet bulb calculator. With 16 universal inputs, the VLCA-1688 economically fills the gap between the VLC-1188 and a VLX with EXP modules in an Alerton system.

Alerton’s VisualLogic Display (VLD) is a communicating sensor-controller combination with built-in temperature and humidity sensors that targets common applications such as roof top units, fan-coil units and heat pumps. It provides a cost-effective solution to meet in-room hotel requirements—an easy-to-use interface, easy-to-see digital display, and Celsius/Fahrenheit change over—where you already have Alerton systems in public or common areas. The VLD-362W features an integrated wireless receiver that communicates to different combinations of sensors for occupancy and detects whether doors and/or windows are open or closed, then reports back to the front end BAS. The Alerton® AZW-5000 provides for the wireless extension of a BACnet network using mesh networking topology to ensure self-healing, reliable communications. The AZW-5000 offers the ability to locate Alerton VisualLogic controllers (VLCs) up to 200 feet away from the nearest wired or wireless connection point.

Three or more AZW-5000s make up a wireless mesh network. Each AZW-5000 on that network supports an MS/TP network with one or more unitary controllers (VLC, VLD, VAV, or MS/TP Microset). VAV Controller.
