AddMe III Modbus I/O


Type:  I/O Interface
Description:  AddMe III provides 32 I/O points in a single Modbus RTU slave device. Universal inputs are configurable as analog or discrete with integer or floating point data available. Data scaling with slope/intercept is supported, and several thermistor linearization tables are built in. This device is optimized for building automation and facility management with thermistor support for temperature input. Relay outputs include HOA switches and status indicators. AddMe Lite is programmable using a structured control language.
Connectivity:  Modbus
Features:  AddMe III features EIA-485 communications as a Modbus RTU slave. AddMe III features 18 universal context sensitive inputs. 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. AddMe III also includes 4 analog outputs, 2 pulse inputs, and 8 Form A relay outputs.
Specifications:  See attached spec. sheet.
