Model AMJR-14-SB
BACnet MS/TP Slave

12 Analog/Universal Inputs
2 Discrete Outputs
RS-485 Serial Port

Control Solutions’ AddMe Lite features 12 inputs which accept analog input from thermistors or 0-10V sensors, or discrete input from dry contact switches. AddMe Lite also provides 2 discrete ouputs which can sink 1A at 24VDC.

Analog Input objects provide data from the analog I/O points. Linearization tables are provided for 10K and 20K type II, III, and IV thermistors. Input type and scaling is configured by writing to object properties. Binary Output objects provide BACnet access to the outputs. An additional 60 writeable Multistate Input objects are available for use by the user's program.

AMJ14SB AddMe Lite Programmable I/O with Modbus RTU $245.00

The online support package you download right here for free includes help pages in browser format, JavaScript sensor calibration tool, Windows device configuration tool, and PL/i compiler. To review the help pages, just click the image above. To download, go to the Downloads page.

AddMe Lite is freely programmable using Control Solutions' PL/i language. The PC based compiler is part of the free configuration tool you download from this web site.

AddMe Lite model AMJR-14-SB is simply an I/O node on the BACnet network until you download a program code file. The program is saved in Flash, and AddMe Lite now becomes a stand alone controller (still a slave on the network).

You can configure AddMe Lite manually by writing to BACnet object properties. The free Windows based configuration tool figures out the properties for you. You simply select options from lists. Click the image below to see the tool close up.
