Model AM3-LN 18 Analog/Universal Inputs 4 Analog Outputs 8 Discrete Outputs 2 Discrete/Pulse Inputs Modbus RTU Gateway LonWorks® I/O for System Expansion

Control Solutions’ AddMe III features 18 universal inputs with changeable network variable types. The universal inputs are context sensitive. When configured as an analog input, the continuously self-calibrating sigma-delta converter produces 15-bit resolution with high noise immunity. When configured as a discrete input, the converter switches to 8-bit resolution at 128 samples per second for fast response.

Network variables for the analog I/O points may be configured for any scalar LonMark SNVT, fixed point or floating point. In addition, analog (universal) inputs may be configured to SNVT_switch with the on threshold programmed via the translation tables. Translation tables allow linearization of type II or type III thermistors or other nonlinear sensors. Either 3K, 10K, or 20K thermistors can be connected directly to analog inputs.

Only LonMark standard variable types and configuration properties are used. The standard LonMark Object plug-in, or LonMaker browser, can be used to do all necessary configuration. Send times for network traffic throttling and heartbeat, send on delta, object override, etc., are all supported per LonMark standards.
