Modbus data acquisitie I/O, D1-15
De D1-15 Modbus data acquisitie modules zijn leverbaar met PT100 en V/mA analoge ingangen. Een 15-bits A/D omvormer wordt gebruikt voor de conversie van analoog naar digitaal. De modules hebben een RS485 of RS422 interface en het communicatieprotocol is Modbus ASCII of RTU en kunnen op een DIN-rail worden gemonteerd.

Beschrijving
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.
