425042.1

Modbus data acquisitie I/O, D1-40A-x

De D1-40A-V en D1-40A-I Modbus data acquisitie modules zijn leverbaar met 6x 0-5 VDC of 6x 4-20 mA ingangen. Een A/D-omzetter met een resolutie van 16 bit 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.

Analog isolated module with 6 common ground input channels (4-20mA)

Beschrijving

The D1-40A-V module provides 6 input channels for reading of 0-5 V analog signals; the double ramp conversion circuit ensures a reliable reading with a 16 bit resolution and a 0.05 % full scale accuracy; the module does not require calibration and mantains its characteristics of accuracy; analog inputs, power section and communication interface are optically isolated; 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 63) can be set through microswitches; the module is suited for mounting on a DIN rail.
