Modbus data acquisition I/O, D1-15
The D1-15 Modbus data acquisitions modules are available with PT100 and V/mA analog inputs. A 15 bit resolution is used for the analog to digital conversion. The modules have a RS485 or RS422 interface and the communication protocol is Modbus ASCII or RTU and can be mounted on a DIN-rail.

Description
The D1-15 module provides 9 input channels for reading of 6 analog signals (0-10 V or 0/4-20 mA) and 3 temperatures through Pt100 sensors (3 wire), with automatic compensation of the cable resistance.
The D1-15A module provides 6 input channels for reading of analog signals, with the possibility to set input type (0-10 V or 0/4-20 mA) for each channel.
The D1-15P module provides 6 input channels for reading of temperature through 2 or 3 wire Pt100 sensors, with automatic compensation of the cable resistance.
The ramp conversion circuit ensures a reliable reading with a 15 bit resolution and a 0.05 % full scale accuracy; the module does not require calibration and mantains its characteristics of accuracy; an internal watch-dog circuit ensures a non-stop operation; interface type (RS422 or RS485), communication protocol (Modbus ASCII or RTU) and address (from 1 to 31) can be set through microswitches; the module is suited for mounting on a DIN rail.
